Properties of CaCO3:-
It is a fluffy powder.
It decomposes to give carbon dioxide when heated up to 1200K.
When it reacts with dilute acid, it liberates carbon dioxide as a by-product.
CaCO3+H2SO4 → CaSO4+H2O+CO2
At 1200K, calcium carbonate decomposes to give carbon dioxide and calcium oxide.
CaCO3 → CaO + CO2
On reacting with dilute acids, calcium carbonate gives carbon dioxide.
CaCO3 + 2HCl → CaCl2 + H2O +CO2
