The equivalent weight of KIO3KIO_{3} in the reaction 2Cr(OH)3+4OH+KIO3→2CrO42−+5H2O+KI2Cr(OH)_{3} + 4OH + KIO_{3} \rightarrow 2CrO_{4}^{2 -} + 5H_{2}O + KI is.

A

Mole wt.

B

Mol. wt.6\frac{\text{Mol. wt.}}{6}

C

Mol. wt.2\frac{\text{Mol. wt.}}{2}

D

Mol. wt.3\frac{\text{Mol. wt.}}{3}

Answer

Mol. wt.3\frac{\text{Mol. wt.}}{3}

Explanation

Solution

Molecular weight3\frac{\text{Molecular weight}}{3}Because in KIO3KIO_{3} effective oxidation number is 3.
