Limestone

The main compound in limestone is Calcium carbonate

The reaction to produce calcium oxide from limestone is thermal decompostition

Calcium hydroxide is produced when calcium oxide reacts with water

Calcium hydroxide is used to neutralise acids because it is an Alkalki

Jobs of Limestone: neutralise excess acidity - which may be caused by acid rain - in lakes and in soils , Limestone is used as a building material, and to purify iron in blast furnaces & It's also used in the manufacture of glass, and of cement (one of the components of concrete).
