Calcium Hydroxide - Ca(OH)2

Calcium hydroxide, commonly known as slaked lime, is defined via the chemical system Ca(OH)2. It is an inorganic compound which has a white, powdery appearance in its strong-nation. However, Ca(OH)2 has a colourless appearance in its crystalline shape.

The change names of this compound encompass hydrated lime, slack lime, pickling lime, and caustic lime. Generally, calcium hydroxide is prepared by using mixing water and calcium oxide (additionally referred to as short lime). You can Get all types of Lime from Rajasthan Lime.

The chemical reaction between sodium hydroxide and calcium chloride dissolved in water (aqueous CaCl2) additionally yields this compound. The shape of a Ca(OH)2 molecule is illustrated underneath.

Physical Properties

Ca(OH)2 has a hexagonal crystal structure. It isn't always very soluble in water and its solubility reduces with an boom in temperature. For example, its solubility at 0oC is 1.89 g/L and its solubility is 1.Seventy three g/L at 20o C

At temperatures drawing close its melting point, this compound has a tendency to lose water and decompose.

The solubility product (Ksp) of calcium hydroxide is 5.Five * 10-6.

Chemical Properties

Ca(OH)2 is pretty soluble in glycerol and acids, however handiest barely soluble in water. 

Limewater reacts with acids and paperwork salts.

The saturated solution of calcium hydroxide in water additionally reacts with and dissolves metals which include aluminium.
