What is produced if an acid is added to a base?
When an acid is added to a base, the acid nullifies the effect of the base, and conversely, the effect of an acid is nullified by a base to give a salt and water. Such a type of reaction between an acid and a base to give a salt and water is known as a neutralisation reaction.
The reaction can be represented as follows.
Acid + Base → Salt + Water
For example, when sodium hydroxide is treated with hydrochloric acid, the reaction can be written as follows.
NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)
