Question

Equivalent mass of $FeC_{2}O_{4}$ in the reaction
$FeC_{2}O_{4} \to Fe^{+3} + CO_{2}$ is $\frac{M}{3}$

• A. M
• B. M/2
• C. M/3
• D. 2M/3

Answer 1

Answer: (C)

$\underset{+2}{F}eC_{2}\underset{+3}{O_{4}} \to F\underset{+3}{e^{+3}} + C\underset{+4}{O_{2}}$
Total change in oxidation:
$1 \times 1+2 \times 1=3$
Eq. wt. =$\frac{M}{3}$
