Thermal Decomposition of Calcium Carbonate (solutions,

Calcium carbonate is heated strongly until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate.Thermal decomposition of calcium carbonate - Stack,Thermal decomposition of calcium carbonate.
