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. $H_{2} {S O}_{4} + N a O H \to {N a H S O}_{4} + H_{2} O$

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

$Z n (s) + 2 N a O H \to {N a}_{2} {Z n O}_{2} (a q) + H_{2} (g)$
