Calcium Carbonate: Definition, Formula, Preparation, Structure
Properties of Calcium Carbonate (CaCO 3) Calcium Carbonate is known as fluffy powder. When heated up to 1200K, it decomposes to form carbon dioxide. It produces carbon dioxide as a by-product when it reacts with dilute acid. Calcium carbonate decomposes to form calcium oxide and carbon dioxide at a temperature of 1200 K.

Since this is a reversible reaction, the carbon dioxide produced is carried out of the kiln (so that it doesn't react back with the calcium oxide to produce calcium carbonate). The calcium oxide is removed at the bottom of the kiln. Calcium oxide (lime) is used to treat acidic soil and industrial waste in order to neutralise it.
