Question

The equivalent weight of KIO3 in the reaction 2Cr(OH)3 +4OH +KIO3 → 2CrO2-4 +5H2O +KI is (A) (Mol. wt./3) (B) (Mol. wt./6) (C) (Mol. wt./2) (D) Molecular weight

Tardigrade Admin · Accepted Answer

(Molecular weight/3) Because in KIO3, effective oxidation number is 3

Q. The equivalent weight of $K I O_{3}$ in the reaction
$2 C r (O H)_{3} + 4 O H + K I O_{3} \to 2 C r O_{4}^{2 -} + 5 H_{2} O + K I$ is

$\frac{M o l . wt .}{3}$

$\frac{M o l . wt .}{6}$

$\frac{M o l . wt .}{2}$

Molecular weight

$\frac{M o l ec u l a r w e i g h t}{3}$ Because in $K I O_{3}$ , effective oxidation number is 3
