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

<chem>2HCl + CaCO3 \rightarrow CaCl2 + CO2 + H2O</chem>

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

<chem>H2SO4 + CaCO3 \rightarrow CaSO4 + CO2 + H2O</chem>

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

<chem>2HNO3 + CaCO3 \rightarrow Ca(NO3)2 + CO2 + H2O</chem>
