Answer
Reaction between a base and an acid to give two new compounds — salt & water — by interchange of radicals is termed double decomposition neutralization reaction.
It is represented as :
For example,
NaOH [Base] + HCl [Acid] ⟶ NaCl [Salt] + H2O [Water]
(a) Insoluble base [oxide] — Copper [II] oxide reacts with sulphuric acid and forms Copper sulphate :
CuO + H2SO4 ⟶ CuSO4 + H2O
(b) A soluble base — Sodium hydroxide reacts with HCl and forms soluble salt (sodium chloride) and water:
NaOH + HCl ⟶ NaCl + H2O
