What happens to the H+ ions, of the solution, when an acid is neutralised?
When a base is added to an acid, it nullifies the effect of the acid and removes the H+ ions from it and turns them into water. During a neutralisation reaction, the H+ ions of an acid are converted into water.
The reaction can be represented as follows.
Acid + Base → Salt + Water
For example, when sodium hydroxide is treated with hydrochloric acid, sodium chloride and water are produced.
NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)
