Preparation of Calcium Hydroxide From quick lime Calcium hydroxide is prepared on a commercial scale by adding water to quicklime. This process is called slaking of lime. CaO + H2O ----> Ca(OH)2 From calcium chloride It is also obtained by treating calcium chloride with caustic soda. Properties of Calcium Hydroxide 1) It is a white amorphous powder … [Read more...] about Calcium Hydroxide

Calcium Oxide
Calcium Oxide Preparation of Calcium Oxide Calcium oxide is called quick lime. It is prepared by heating limestone in a rotatory kiln at 1070-1270 K. CaCO3 ⇔ CaO + CO2 ΔH = 179.9 KJ Since the reaction is reversible, therefore, the carbon dioxide is removed as soon as it is formed to enable the reaction to proceed to completion. The temperature is not … [Read more...] about Calcium Oxide
