Solution

The equation of chemical reaction taking place when hard water containing calcium chloride is passed through permutit is as shown.
$N a_{2} Z e permutit + C a^{2 +} \to C a Z e Exhausted permutit + 2 N a^{+}$
$C a^{2 +}$ ions from hard water are replaced with $N a^{+}$ ions from permutit.
