Hydrated lime

الوصف

Calcium hydroxide, traditionally called slaked lime, hydrated lime, or pickling lime, is a chemical compound with the chemical formula Ca(OH)2. It is a colourless crystal or white powder, and is obtained when calcium oxide (called lime or quicklime) is mixed, or slaked with water. It can also be precipitated by mixing an aqueous solution of calcium chloride and an aqueous solution of sodium hydroxide.

Because of its strong basic properties, calcium hydroxide has many and varied uses:
* A flocculant, in water and sewage treatment and improvement of acid soils
* An ingredient in whitewash, mortar, and plaster
* An alkali used as a lye substitute in no-lye hair relaxers
* A chemical depilatory agent found in Nair
* An ingredient in baby formula milk
* A chemical reagent
