Calcium hydroxide is moderately soluble in water, as seen for many dihydroxides. Its solubility increases from 0.66 g/L at 100 °C to 1.89 g/L at 0 °C. [8] Its solubility product K sp of 5.02 × 10 −6 at 25 °C, [1] its dissociation in water is large enough that its solutions are basic according to the following dissolution reaction:
This page provides supplementary chemical data on calcium hydroxide. Material Safety Data Sheet ... Density: 2.2 g cm −3 [2] Solubility in H 2 O 0.160 20 g/100 g [2]
The hydroxyapatite nanocrystal suspension can be prepared by a wet chemical precipitation reaction following the reaction equation below: [11] 10 Ca(OH) 2 + 6 H 3 PO 4 → Ca 10 (PO 4) 6 (OH) 2 + 18 H 2 O. The ability to synthetically replicate hydroxyapatite has invaluable clinical implications, especially in dentistry.
Calcium oxide (formula: Ca O), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic , alkaline , crystalline solid at room temperature . The broadly used term lime connotes calcium-containing inorganic compounds , in which carbonates , oxides , and hydroxides of calcium, silicon , magnesium ...
The International Mineralogical Association recognizes lime as a mineral with the chemical formula of CaO. [2] ... Ca(OH) 2 + CO 2 → CaCO 3 + H 2 O.
The reaction of CaH 2 with water can be represented as follows: CaH 2 + 2 H 2 O → Ca(OH) 2 + 2 H 2. The two hydrolysis products, gaseous H 2 and Ca(OH) 2, are readily separated from the dried solvent. Calcium hydride is a relatively mild desiccant and, compared to molecular sieves, probably inefficient. [7]
Calcium iodide (chemical formula CaI 2) is the ionic compound of calcium and iodine. This colourless deliquescent solid is a salt that is highly soluble in water. Its properties are similar to those for related salts, such as calcium chloride. It is used in photography. [1] It is also used in cat food as a source of iodine.
