Reactions of acids with carbonates

A , water and carbon dioxide are produced when acids react with carbonates. In general:

Acid + carbonate → salt + water + carbon dioxide

For example:

Hydrochloric acid + copper carbonate → copper chloride + water + carbon dioxide

2HCl(aq) + CuCO₃(s) → CuCl₂(aq) + H₂O(l) + CO₂(g)

Other carbonates also react with dilute acids. For example:

Sulfuric acid + magnesium carbonate → magnesium sulfate + water + carbon dioxide

H₂SO₄(aq) + MgCO₃(s) → MgSO₄(aq) + H₂O(g) + CO₂(g)

Question

Name the products of the reaction of zinc carbonate with hydrochloric acid.

Question

Name the products of the reaction between zinc carbonate and sulfuric acid, and write a balanced symbol equation for the reaction.

Testing for carbon dioxide gas

Carbon dioxide gas can be identified by bubbling it through limewater. Limewater is a dilute solution of calcium hydroxide. Limewater is colourless, but when it is mixed with carbon dioxide, it turns cloudy.
