Calcium Carbonate

Key Stage 3

Meaning

Calcium Carbonate is a solid (at room temperature) chemical compound with the formula CaCO₃.

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

Sulphuric Acid + Calcium Carbonate → Calcium Sulphate + Carbon Dioxide + Water

Nitric Acid + Calcium Carbonate → Calcium Nitrate + Carbon Dioxide + Water

Key Stage 4

Meaning

Calcium Carbonate is a solid (STP) chemical compound with the formula CaCO₃.

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
