Solution

The correct option is A $1.5$
Two electrons are involved in the following reaction.
$N a C l O_{3} + H_{2} O \to N a C l O_{4} + H_{2}$
This is because, the oxidation number of chlorine changes from $+ 5$ to $+ 7$ .
Thus 2 faraday of charge will form one mole of $N a C l O_{4}$ .
3 faraday of charge will form $\frac{1}{2} \times 3 = 1.5$ mole of $N a C l O_{4}$ .
