Calcium hydroxide is modestly 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:
An example is when slaked lime (calcium hydroxide) is mixed into a thick slurry with sand and water to form mortar for building purposes. When the masonry has been laid, the slaked lime in the mortar slowly begins to react with carbon dioxide to form calcium carbonate (limestone) according to the reaction: Ca(OH) 2 + CO 2 → CaCO 3 + H 2 O.
Whitewash, calcimine, kalsomine, calsomine, asbestis or lime paint is a type of paint made from slaked lime (calcium hydroxide, Ca(OH) 2) or chalk (calcium carbonate, CaCO 3), sometimes known as "whiting". Various other additives are sometimes used.
This page provides supplementary chemical data on calcium hydroxide. Material Safety Data Sheet The handling of this chemical may incur notable safety precautions. ...
Lime softening produces large volumes of a mixture of calcium carbonate and magnesium hydroxide in a very finely divided white precipitate which may also contain some organic matter flocculated out of the raw water. Processing or disposal of this sludge material may be an additional cost to the process. Drying and re-calcining the waste allows ...
