Question

What is the equivalent mass of IO4- when it is converted into I2 in acid medium (A) M/6 (B) M/7 (C) M/5 (D) M/4

Tardigrade Admin · Accepted Answer

Equivalent mass=(Molecular weight/Change in oxidation number per mole) Suppose molecular weight is M Oxidation number of I2 in I4- in Acidic medium i.e., I × (-8 ) + 1e- = + 7 So eq. wt. = M/7

Q. What is the equivalent mass of $I O_{4}^{-}$ when it is converted into $I_{2}$ in acid medium

$M /6$

$M /7$

$M /5$

$M /4$

Equivalent mass $= \frac{M o l ec u l a r w e i g h t}{C han g e in o x i d a t i o n n u mb er p er m o l e}$
Suppose molecular weight is M
Oxidation number of $I_{2}$ in $I_{4}^{-}$ in
Acidic medium i.e., $I \times (- 8) + 1 e^{-} = + 7$
So eq. wt. $= M /7$
