Calcium hydroxide (Ca(OH)2) is a soft white powder that is extensively used as a raw ingredient in the chemical industry. It is formed after calcium oxide has been combined with water. It has two hydroxide Ions (OH) for each calcium ion (Ca2+). The chemical is ionic with electrolytic and aqueous dissociations, both of which produce calcium ions and hydroxide.
It is known by numerous names, including hydrated lime, slaked lime, cal, and picking lime. Calcium hydroxide is utilized in numerous applications, such as food preparation, and is classified in the form of the E code E526. Limewater is also known as lime milk, is the most common term used to describe the water-based solution that is saturated that contains calcium hydroxide.
A few of the most significant properties can be shown below.

Calcium hydroxide is typically made by reaction of Calcium oxide (CaO) with water (H 2O). The chemical reaction is exothermic in nature, meaning that an enormous amount of heat is produced.
CaO + H 2O + H 2O = Ca(OH) 2
As part of treating sewage, the calcium hydroxide is utilized to clarify the water.
Calcium hydroxide can provide many advantages, such as:
