Determining the Ksp of Calcium Hydroxide AP Lab with vernier
Determining the Ksp of Calcium Hydroxide Calcium hydroxide is an ionic solid that is sparingly soluble in water. A saturated, aqueous, solution of Ca(OH)2 is represented in equation form as shown below. Ca(OH)2 (s) ↔ Ca2+ (aq) + 2OH– (aq) The solubility product expression describes, in mathematical terms, the equilibrium that is established between the solid substance and its dissolved ions in an aqueous system. The equilibrium expression for calcium hydroxide is shown below. Ksp = [Ca2+][OH–]2 The constant that illustrates a substance’s solubility in water is called the Ksp. All compounds, even the highly soluble sodium chloride, have a Ksp. However, the Ksp of a compound is commonly considered only in cases where the compound is very slightly soluble and the amount of dissolved ions is not simple to measure.

Ksp is really just an equilibrium constant (Keq), but it's for a solid dissolving in water. This is special, since all of the reactants are solid, and so they AREN'T included in the equilibrium expression.

Soluble and Insoluble Compounds Chart - Solubility Rules Table - List of Salts & Substances
This chemistry video tutorial focuses the difference between soluble and insoluble compounds. It contains a table or chart of the solubility rules and it provides a list of salts and substances - some of which are soluble while others are insoluble. This video contains a worksheet of examples and problems toward the end of the video including answers and solutions. Here is a list of topics: 1. Understanding The Solubility Rules Table 2. Ions that are always soluble - Na+, K+, Li+, NH4+, C2H3O2-, Cs+, Rb+, ClO4-, ClO3-, and HCO3- 3. Ions that are generally soluble - Cl-, Br-, I- (halides) - Exceptions - Pb2+, Ag+, Hg2 2+ 4. Sulfates are generally soluble except with Ba2+, Ca+2, and Sr2+ 5. The difference between soluble and insoluble compounds - aqueous vs solid phases 6. Substances that are generally insoluble - Hydroxides, carbonates, sulfides, and phosphates
Equation for Calcium Hydroxide Dissolving in Water   | Ca(OH)2 + H2O
In this video we will describe the equation Ca(OH)2 + H2O and write what happens when Ca(OH)2 is dissolved in water. Note: Calcium hydroxide is not very soluble in water (15 mg/L at 25°C). So only a small amount would dissolve. When Ca(OH)2 is dissolved in H2O (water) it will dissociate (dissolve) into Ca +2 and Cl- ions. To show that they are dissolved in water we can write (aq) after each. The (aq) shows that they are aqueous – dissolved in water. The equation for Ca(OH)2 (Calcium hydroxide) and H2O sometimes isn’t considered a chemical reaction since it is easy to change the Ca 2+ and OH- back to Ca(OH)2 (just let the H2O evaporate). At the same time, the Ca(OH)2 is a very different substance than Ca 2+ and OH-.

It was mixed with crushed terracotta as an aggregate and formed into a cube. The cement set hard after 3 days and did not dissolve in water after this period. Process: First I burnt bark and leaves in a kiln at high temperatures to produce well burnt, mostly white wood ash. The ash was then mixed into water and stirred well. The excess water was poured off and the resulting paste was made into pellets and allowed to dry. A pellet was then re-heated in the forge until it glowed about orange hot. This was then taken out, cooled and dropped in a pot of water. The pellet dissolved and boiled due to a chemical reaction with the water. The paste was stirred and crushed terracotta (old tiles from previous projects) was added and mixed to form a mouldable mortar. This was formed into a cube and allowed to set for three days (in the video, a cube made exactly the same way 3 days previously was used due to time constraints). The resultant cube was strong and made a slight ringing sound when tapped with a finger nail. It was placed in water for 24 hours to simulate a very heavy rain event and did not dissolve or release residues into the water. My current theory: The main component of wood ash consists of calcium in some form (e.g. calcium carbonate, calcium oxide). This can be up to 45% from my research. Calcium is in higher concentration in the bark and leaves of a tree. When the ash is mixed with water, the soluble component of wood ash (10% pot ash) dissolves into the water. But seeing that it does nothing for the cementing process, it is drained off leaving the insoluble calcium (and other components) in the paste. Doing this probably raises the relative percentage of calcium in the paste to about 50% or more. Most of the other 50 % consists of silica and alumina which are pozzolans, materials that chemically react with calcium hydroxide to increase the durability of the cement product. The paste was then made into a pellet and fired again to high temperature to convert all the calcium compounds to calcium oxide. It also reduces any charcoal in the pellet to ash if it hadn’t already been burnt the first time. This step seemed important as un-fired ash pellets only partially hardened and would fall apart in water, though retaining a weak undissolved 5mm thick crust. I can only surmise that re-firing the ash just gave a greater conversion of the calcium components to calcium oxide. The pellet is slaked in water converting the calcium oxide to calcium hydroxide. This cement was mixed with crushed terracotta which may also help in some way that I’m not aware of as I only did this one experiment and did not test other aggregates yet (e.g. sand, gravel etc.). Terracotta is porous and might hold together better than other materials. The mixture is allowed to set in air where carbon dioxide reacts with calcium hydroxide to form calcium carbonate cementing the aggregate together. After this, the cement will not dissolve in water. Use: I think this material might have a potential use as a mortar holding rocks or bricks together in wet environments where limestone or snail shells are unavailable for making cement. Wood ash is a pretty ubiquitous material to most natural environments inhabited by people using biomass fuels. Wood ash cement turns a waste product into a valuable building material. From my research, wood ash is already being used as a partial replacement for cement in the building industry without decreases in strength of the final product. But I’ve only just started experimenting with it and don’t know its full capabilities and limitations. Calcium content of wood ash differs depending on the species of tree, the part of the tree burnt and the soil it’s grown on. Cautious experimentation is still required before committing to a hut built from this material.

Potassium Hydroxide Dissolves Chicken To The Bone
I use caustic potassium lye, also known as caustic potash to dissolve chicken flesh. First I don the appropriate protective gear to deal with such a caustic solution. Then I pour out about 200 g of potassium hydroxide and add it to about 1.5 cups of water As I am adding the KOH the water instantly begins to boil as the KOH dissolving in water is highly exothermic. After I put in all of the KOH I measure the temperature of the water to be very near boiling, about 205°F. I then add the chicken wing into the caustic solution. I explain that the hydroxide ions will essentially turn the chicken into soap. This works by breaking down the fat molecules in the cell walls and turning them into glycerol and soap molecules. Watch the fat and meat slowly turn to gel as the potassium hydroxide reacts with the flesh. Eventually the entire chicken wing dissolves into a gelatinous mass. In the end I show the final product that used to be meat is a transparent soft gel. I do make a mistake some have pointed out by saying the cells of the chicken flesh have cell walls. Really I just mean the lipid bilayer (cell membrane). Not a true cell wall like in plant cells. Here is some more info on potassium hydroxide from Wikepedia: Along with sodium hydroxide (NaOH), this colorless solid is a prototypical strong base. It has many industrial and niche applications, most of which exploit its corrosive nature and its reactivity toward acids. An estimated 700,000 to 800,000 tonnes were produced in 2005. Approximately 100 times more NaOH than KOH is produced annually.[9] KOH is noteworthy as the precursor to most soft and liquid soaps as well as numerous potassium-containing chemicals. Potassium hydroxide can be found in pure form by reacting sodium hydroxide with impure potassium. It is usually sold as translucent pellets, which will become tacky in air because KOH is hygroscopic. Consequently, KOH typically contains varying amounts of water (as well as carbonates, see below). Its dissolution in water is strongly exothermic. Concentrated aqueous solutions are sometimes called potassium lyes. Even at high temperatures, solid KOH does not dehydrate readily.[10] Potassium hydroxide solutions with concentrations of approximately 0.5 to 2.0% are irritating when coming into contact with the skin, while concentrations higher than 2% are corrosive. Historically KOH was made by adding potassium carbonate (potash) to a strong solution of calcium hydroxide (slaked lime), leading to a metathesis reaction which caused calcium carbonate to precipitate, leaving potassium hydroxide in solution: Ca(OH)2 + K2CO3 → CaCO3 + 2 KOH Filtering off the precipitated calcium carbonate and boiling down the solution gives potassium hydroxide ("calcinated or caustic potash"). It was the most important method of producing potassium hydroxide until the late 19th century, when it was largely replaced by the current method of electrolysis of potassium chloride solutions.[9] The method is analogous to the manufacture of sodium hydroxide (see chloralkali process): 2 KCl + 2 H2O → 2 KOH + Cl2 + H2 Hydrogen gas forms as a by-product on the cathode; concurrently, an anodic oxidation of the chloride ion takes place, forming chlorine gas as a by-product. Separation of the anodic and cathodic spaces in the electrolysis cell is essential for this process. USES KOH and NaOH can be used interchangeably for a number of applications, although in industry, NaOH is preferred because of its lower cost. ike sodium hydroxide, potassium hydroxide attracts numerous specialized applications, virtually all of which rely on its properties as a strong chemical base with its consequent ability to degrade many materials. For example, in a process commonly referred to as "chemical cremation" or "resomation," potassium hydroxide hastens the decomposition of soft tissues, both animal and human, to leave behind only the bones and other hard tissues.[19] Entomologists wishing to study the fine structure of insect anatomy may use a 10% aqueous solution of KOH to apply this process.[20] In chemical synthesis, the choice between the use of KOH and the use of sodium hydroxide, NaOH, is guided by the solubility of the resulting salt. The corrosive properties of potassium hydroxide make it a useful ingredient in agents and preparations that clean and disinfect surfaces and materials that can themselves resist corrosion by KOH.[21] KOH is also used for semiconductor chip fabrication. Potassium hydroxide is often the main active ingredient in chemical "cuticle removers" used in manicure treatments. Because aggressive bases like KOH damage the cuticle of the hair shaft, potassium hydroxide is used to chemically assist the removal of hair from animal hides. The hides are soaked for several hours in a solution of KOH and water to prepare them for the unhairing stage of the tanning process. This same effect is also used to weaken human hair in preparation for shaving.

In this activity we explore the nature of metallic oxides. By burning a strip of magnesium, we obtain magnesium oxide which we then dissolve in water. We test this magnesium oxide solution with litmus paper. The solution does not affect blue litmus but turns red litmus blue. This tells us that magnesium oxide is basic or alkaline in nature. In general, metal oxides are basic in nature.

Chemistry Experiment How To Make Calcium Carbonate Full HD video
In this experiment I will show you how to make Calcium Carbonate. This compound is present in many rocks because they are remains of prehistoric sea living animals with shells, living hundred millions years ago. But it's available for free in quite pure form in the thing that we normally throw away to trashcan. Eggshells. It has mass approximately 5-6 grams. Therefor there is needed approximately 200 eggshells to receive 1 kg of Calcium Carbonate. My videos are often watched by people from India, Pakistan, and other 3rd world countries. You can make job from this process. Buy eggshells from people and convert them to Calcium Carbonate, Calcium Oxide, Calcium Hydroxide and sell ready product. First I will use coffee mixer like this one and mix shells. Press button and release multiple times until you have dust. Then use mortar and pestle to mash it up even more. Once you have dust place it in container and add water. Calcium Carbonate is slightly soluble in water. Whatever is insoluble and lighter than water will gather on the surface of water. Wait a day and throw it away. Repeat multiple times with more eggshells. At the bottom of tank there is our product. I have here product made couple days ago. Get rid of water and you have Calcium Carbonate. In future I will show how to make from it Calcium Oxide, Calcium Hydroxide and other Calcium compounds. Thank you for watching. ps. Use dry eggshells. Fresh one are a bit wet. Wait at least day or two prior mixing them in coffee mixer. ps2. You can convert it even more, by dissolving entire eggshells permanently in water (there is needed plentiful of water). Then heat water to vaporize it (use Sun to minimize cost). Remains will be looking nothing like original material.

Reaction of Calcium Hydroxide and Copper Sulfate in Water
In this video we demonstrate the reaction between Calcium Hydroxide and Copper Sulfate (CuSo4 + Ca(OH)2 = Cu(OH)2 + CaSo4). This is a double replacement reaction that precipitates both products. As usual, we don't own the music, and don't try this at home.

What are endothermic and exothermic reactions | Chemistry for All | FuseSchool
An exothermic reaction gives off energy to the surroundings; like a fire giving off heat. An endothermic reaction takes in energy from the surroundings; like a snowman melting. Exothermic reactions transfer energy to the surroundings, and this energy is usually heat energy, they cause the surroundings to heat up. Just like a bonfire keeping everyone warm. As well as combustion (burning), other examples of exothermic reactions are: - Neutralisation reactions between acids and alkalis - The reaction between water and calcium oxide - Respiration. It is easy to detect an exothermic reaction - just get your thermometer and see if the temperature increases. Most chemical reactions are exothermic, because heat is given out. Physical processes can also be endothermic or exothermic. When something freezes, it goes from liquid to solid. Bonds need to be made for this to happen, and to make bonds you need to do some work, thus energy is given out and freezing is exothermic. Similarly, when condensation happens - because a gas is going to liquid, again bonds need to be made and so energy is given out. So freezing and condensation are exothermic. Because in exothermic reactions, energy is given out to the surroundings. This means that the energy of the reactants is higher than the energy of the products. Endothermic reactions are less common. They take in energy from the surroundings. The energy being transferred is usually heat. So in endothermic reactions, the surroundings usually get colder. Some examples of endothermic reactions are: - Electrolysis - The reaction between sodium carbonate and ethanoic acid - Photosynthesis. Endothermic reactions can also be seen in physical processes. When something melts it goes from a solid to a liquid. For this to happen, bonds need to be broken. And to break bonds, energy needs to be put in. Boiling is also endothermic because energy needs to be put in to break the bonds for the liquid to turn to gas. Because in endothermic reactions, energy is added to the reaction, the energy of the products is higher than the energy of the reactants. And again, we can detect endothermic reactions with a thermometer because the temperature would get colder. SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos.

Funded by MeitY (Ministry of Electronics & Information Technology) Saponification: The process of Making Soap :- The term saponification is the name given to the chemical reaction that occurs when a vegetable oil or animal fat is mixed with a strong alkali. The products of the reaction are two: soap and glycerin. The name saponification literally means "soap making". Different oils are used in saponification process. Coconut oil creates lots of glycerin, makes big bubbly lather, and is very stable. Olive oil has natural antioxidants and its soap makes a creamier lather. The alkali used in soap is either potassium hydroxide, which is used to make soft soap or liquid soap because of its greater solubility, or sodium hydroxide, which is used to make hard soap. This video explains the preparation of soap by saponification reaction.
