Hydrated Lime, Molar Mass : 74.093 g/mol

Hydrated Lime (or calcium hydroxide, or slaked lime) is usually a dry powder resulting from the controlled slaking of quicklime with water. The exothermic or released heat of reaction is captured and used to evaporate the excess slaking water. For "slurry lime" excess water is not evaporated and the hydrate remains as a water suspension.
Hydrated Lime is manufactured through the lime or we can say that the Limestone is the raw material of Hydrated Lime. Hydrated Lime is available in various percentages varying from 60% to 90% the mostly used percentage of Hydrated Lime is 80 % and 85 % rest is made according to the requirements and orders of the factory. Hydrated Lime has magnesium, silica, iron, aluminum and calcium carbonate and other impurities. The color, mesh value as well as the percentage of iron, aluminum, silica and other impurities varies according to the percentage of hydrate lime. The best type of Hydrated Lime is that in which there is less percentage of impurities and other materials.
Hydrated Lime is used in medical field in the medicines, used in paints to make paints, used in dyes to make colors. Hydrated Lime is the cheapest pollution controller as it purifies the wastewater of the factories. Hydrated Lime is used in the steel industry as influent, used in sugar and paper industries to purify and cleaning of sugar and paper. Hydrated Lime is used to form carbides & used as the raw material in bleaching industry.
These are the benefits of hydrated lime that it is used in modern scientific society.
Hydrated Lime is manufactured as under :

• CaCO₃ - (ignition) from 900* to 1000* CaO + CO₂

          Limestone =  Lime + carbon dioxide

• CaO + H₂O= Ca(OH)₂

          Lime + water = Calcium Hydroxide (Hydrated Lime)
