They combine to form water
A neutralisation reaction is a type of chemical reaction whereby an acid and base reacts in an aqueous solution
to form salt and water only.
For example, the acid HCl reacts with the base NaOH to give salt (NaCl) and water (H2O).
Positive sodium ions from NaOH and negative chloride ions from HCL combine to form the salt sodium chloride (NaCl).
While the H+ from the acid and OH− from base combine to form water.
Therefore, when HCl and NaOH react in an aqueous solution the H+ and OH− combine to form water.
