Question

What happens to the H⁺ ions, of the solution, when an acid is neutralised?

Answer 1

When a base is added to an acid, it neutralises the acid and removes H⁺ ions, forming water. During a neutralisation reaction, the H⁺ ions of an acid are converted into water.
The reaction can be represented as follows.

\[\ce{Acid + Base -> Salt + Water}\]

When sodium hydroxide is treated with hydrochloric acid, sodium chloride and water are produced.

\[\ce{NaOH_{(aq)} + HCl_{(aq)} -> NaCl_{(aq)} + H2O_{(l)}}\]
