Question

With the help of suitable examples explain the term neutralization and the formation of –

1. acidic,
2. basic and
3. neutral salts

Answer 1

Neutralization is a type of chemical reaction in which an acid and base react to form salt and water with the evolution of heat.

1. When the neutralization of a strong acid with a weak base takes place, it leads to the formation of acidic salt.
   Example:
   \[\ce{HCl +NH4OH -> NH4Cl  +H2O}\]
2. When the neutralization of a weak acid with a strong base takes place, it leads to the formation of basic salt.
   Example:
   \[\ce{NaOH + CH3COOH -> CH3COO^-Na^+ + H2O}\]
3. When the neutralization of a strong acid with a strong base takes place, it leads to the formation of neutral salt.
   Example:
   \[\ce{NaOH + HCl -> NaCl + H2O}\]
