Before we delve into the various uses of calcium hydroxide, we shall first of all explain what is chemical compound is and the kind of chemical reactions it undergoes. Calcium hydroxide, Ca(OH)2 also known as slaked lime is manufactured by heating limestone to a high temperature of about 10000C and then adding water to the calcium oxide. Calcium hydroxide is slightly soluble in water; it is an alkaline solution and is known as lime water. Calcium hydroxide is a strong base. It neutralizes acids and displaces ammonia from ammonium salts and decomposes on heating to give the oxide.
Uses of Calcium Hydroxide
Calcium hydroxide is of great importance to chemist, engineers, agriculturists, biologists and engineers. This compound has found several uses in industrial production processes and in the laboratory. Some of the uses of calcium hydroxide are enumerated below.
Calcium hydroxide otherwise known as slaked lime is a cheap alkali commonly used in treating acidic soils.
A suspension of calcium hydroxide in water, known as milk of lime, is used as white wash. Lime water is used as a test for carbon(IV) oxide in the laboratory.
Bleaching powder is manufactured by passing chlorine over moist calcium hydroxide.
Calcium hydroxide is used to recover ammonia from ammonium chloride in the Solvay process. It is commonly used in the laboratory preparation of ammonia.
