Calcium hydroxide, traditionally called slaked lime, is an inorganic compound with the chemical formula Ca(HO)2. It is a colorless crystal or white powder and is obtained when calcium oxide is mixed, or "slaked" with water. Calcium hydroxide is used in many applications, including food preparation. Limewater is the common name for a saturated solution of calcium hydroxide.
When heated to 512 °C, the partial pressure of water in equilibrium with calcium hydroxide reaches 101 kPa, which decomposes calcium hydroxide into calcium oxide and water.
Ca(OH)2 CaO + H2O
A suspension of fine calcium hydroxide particles in water is called milk of lime. The solution is calledlimewater and is a medium strength base that reacts with acids and attacks many metals. Limewater turns milky in the presence of carbon dioxide due to formation of calcium carbonate, a process calledcarbonatation:
Ca(OH)2 + CO2 CaCO3 + H2O
Application:
It is utilized in bleaching agent,lemon acid,empoxy propane,leather process,metal production, water treatment,refuse incineration,purification of sugar juices,ect
