Properties

Calcium hydroxide overview

Calcium hydroxide: molecular formula Ca (OH) 2, relative molecular weight 74, MP 580 ° C, pH 212, strongly basic, white powder, can dissolve in water, can dissolve in acid, glycerin, sugar, ammonium chloride, can dissolve in acid to release a large amount of heat, relative density 2.45, its clear aqueous solution is a colorless, odorless, alkaline clear liquid, Placed in air to gradually absorb carbon dioxide to become calcium carbonate.

The application of Calcium hydroxide

Calcium hydroxide is mainly applied in environmental-friendly wastewater treatment, sludge conditioning, flue gas desulfurization, tannery leaching, materials raw materials, paint making, non-metallic smelt, word material addition, calcium based lipids, dyes, freezers and so on.

Properties

Calcium hydroxide, the chemical formula Ca (OH) 2, commonly known as slaked lime, lime water, slaked lime or burnt lime, is a white solid slightly soluble in water, the aqueous solution of which is often known as lime water (in large amounts, lime milk or lime slurry may be formed), which is alkaline and absorbs carbon dioxide and water and so forth in the air to become metamorphic and is generally known to be water-absorbing and is generally used in the modification of construction or in acidic lands.
