The effect of a base is nullified by an acid and vice-versa. The reaction taking place is written as –
NaOH (aq) + HCl (aq) → NaCl (aq) + H2O (l)
The reaction between an acid and a base to give a salt and water is known as a neutralisation reaction. In general, a neutralisation reaction
can be written as –
Base + Acid → Salt + Water
