Question

a. What is a neutralisation reaction? Give an example to show the
formation of a neutral salt.
b. Show the formation of and acidic and a basic salt by
neutralisation.

Answer 1

Explanation:

A :- A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water.

For example, Acid + Base —-> Salt + Water i. e. NaOH (Sodium Hydroxide, a base) + HCl (Hydrochloric acid, an acid) ——> NaCl (Salt) + H2O (Water)

B :- Sodium hydroxide is a base and hydrochloric acid is an acid. When solution of sodium hydroxide is mixed with the solution of hydrochloric acid, both neutralize each other and common salt (Sodium chloride) is formed. Since, it is an exothermic reaction, so reaction mixture becomes slightly hot. The reaction involved in this can be written as follows:

HCl + NaOH → NaCl + H2O

Answer 2

When an acid reacts with a base to give a salt and water, it's called a neutralization reaction.

eg. of formation of neutral salt

HCl + NaOH --> NaCl + H2O

Here , NaCl is a neutral salt.

eg. of formation of acidic salt

H2SO4 + Zn(OH)2 --> ZnSO4 + H2O

Here, ZnSO4 is an acidic salt

eg. of formation of basic salt

CH3COOH + NaOH --> CH3COONa + H2O

Here, CH3COONa is a basic salt.
