Solution

The correct option is A 21
ANS; A
$F e_{3} O_{4}$ is a spinal in this 1 Fe ion in +2 oxidation state
and 2 Fe ion in +3 oxidation state are exist.
equivalent weight of $F e^{+ 3}$ ion = $\frac{55.8}{3}$ = 18.6
equivalent weight of $F e^{+ 2}$ ion = $\frac{55.8}{2}$ = 27.9

then equivalent weight of $F e_{3} O_{4}$ = $\frac{18.6 + 18.6 + 27.9}{3}$
= 21.7
