MCQ
In the following reaction, which choice has value twice that of the equivalent mass of the oxidising agent
  • A
    $64$
  • ✓
    $32$
  • C
    $16$
  • D
    $48$
✓

Answer

Correct option: B.
$32$
b
(b)$\mathop {S{O_2}}\limits_{ + 4} + 2{H_2}O \to \mathop S\limits_0 + 2{H_2}{O_2}$$EW = \frac{M}{4} = \frac{{64}}{4} = 16$;

Twice $16 \times 2 = 32$
