Question

Write chemical equations to show what happens when an acid reacts with a carbonate; also write the name of the main product formed.

Answer 1

When an acid reacts with carbonate, it produces salt (main product), water (H₂O), carbon dioxide (CO₂) gas.

General Equation: \[\ce{Acid + Carbonate -> Salt + Water + Carbon dioxide}\]

Example: \[\ce{CaCO3 + 2HCl −> CaCl2 + H2O + CO2 ^}\]

Calcium carbonate reacts with hydrochloric acid to form calcium chloride (CaCl₂) as the main product (salt), along with water (H₂O) and carbon dioxide (CO₂) gas.

Main product formed: Salt [Calcium chloride (CaCl₂)]
