About Calcium Carbonate
- Calcium Carbonate is a base.
- Calcium Carbonate reacts with acids to produce a Calcium salt, Carbon Dioxide and Water.
- Hydrochloric Acid + Calcium Carbonate → Calcium Chloride + Carbon Dioxide + Water
- 2HCl + CaCO3 → CaCl2 + CO2 + H2O
- Sulphuric Acid + Calcium Carbonate → Calcium Sulphate + Carbon Dioxide + Water
- H2SO4 + CaCO3 → CaSO4 + CO2 + H2O
- Nitric Acid + Calcium Carbonate → Calcium Nitrate + Carbon Dioxide + Water
2HNO3 + CaCO3 → Ca(NO3)2 + CO2 + H2O
