Calcium Hydroxide

Calcium hydroxide, traditionally called slaked lime, is an inorganic compound with the chemical formula Ca(OH)2. It is a colorless crystal or white powder and is obtained when calcium oxide (called lime or quicklime) is mixed, or "slaked" with water. It has many names including hydrated lime, builders' lime, slack lime, Choona (word used in India, Pakistan and Afghanistan), cal, or pickling lime. Calcium hydroxide is used in many applications, including food preparation. Limewater is the common name for a saturated solution of calcium hydroxide.
==Limewater==
Limewater is the common name for a saturated solution of calcium hydroxide. Calcium hydroxide, Ca(OH)2 is sparsely soluble in water (1.5 g dm−3 at 25 °C.) Pure limewater is clear and colorless, with a slight earthy smell and an alkaline bitter taste of calcium hydroxide. The term lime refers to the alkaline mineral, and is unrelated to the acidic fruit.
Limewater is prepared by stirring excess calcium hydroxide in pure water, and filtering off the excess insoluble Ca(OH)2. When excess calcium hydroxide is added to limewater, a suspension of calcium hydroxide particles remains, giving it a milky aspect, in which case it has the common name of milk of lime. Milk of lime is an alkaline solution with a pH of 12.3.
