Because of its weak basic properties, calcium hydroxide has many and varied uses:
As flocculant, in water and sewage treatment and improvement of acid soils
An ingredient in whitewash, mortar, and plaster
In the tanning industry for neutralization of acid, the liming of hides and skins
In the food industry for processing of water (soft drinks)
As a filler in the manufacture of brake pads, ebonite, paints, rubber for preparation of dry mixes for painting and decorating
Slaked lime is useful as a cheap alkali for removal of acid gases from industrial gaseous emissions, for example, coal gas purification, and absorption of chlorine and recovery of ammonia in the Solvay process.
It is supplied in the packing of 22 – 25 kg Paper bags.
