    The equivalent weight of \[KI{{O}_{3}}\] in the reaction \[2Cr{{(OH)}_{3}}+4OH+KI{{O}_{3}}\to 2CrO_{4}^{2-}+5{{H}_{2}}O+KI\] is [MP PMT 2004]

    A)                 Mole wt.             

    B)                 \[\frac{\text{Mol}\text{. wt}\text{.}}{\text{6}}\]

    C)                 \[\frac{\text{Mol}\text{. wt}\text{.}}{\text{2}}\]             

    D)                 \[\frac{\text{Mol}\text{. wt}\text{.}}{\text{3}}\]

    Correct Answer: D

    Solution :

                    \[\frac{\text{Molecular weight}}{3}\] Because in \[KI{{O}_{3}}\] effective oxidation number is 3.
