2. Write an equation for preparation of aqueous salt.
3. What will happen when bases react with metals? [3 MARKS]

Answer 1

Each point: 1 Mark

1. The salts which are obtained by the partial replacement of ionisable hydrogen atoms of a polybasic acid by a metal or an ammonium ion are called acid salts.

2. ${\text{H}}_2{\text{SO}}_4+\text{NaOH}\to {\text{NaHSO}}_4+{\text{H}}_2\text{O}$

3. Bases react with some metals to liberate hydrogen gas.

$\text{Zn}+2\text{NaOH}\to {\text{Na}}_2{\text{ZnO}}_2+{\text{H}}_2$
