Solution

Q.
A sample of a metal oxide has formula $M_{0.83} O_{1.00}$ . The metal M can exist in two oxidation states +2 and +3. In the sample of $M_{0.83} O_{1.00}$ , the percentage of metal ions existing in +2 oxidation state is _______ % (nearest integer). [2023]

Ans.
(59)

$Let no. of ions of M^{+ 2} = x$

$M^{+ 3} = 0.83 - x$

$2 x + 3 (0.83 - x) + 1 (- 2) = 0$

$2 x + 2.49 - 3 x - 2 = 0$

$x = 0.49$

$% M^{2 +} ions = \frac{0.49}{0.83} \times 100 = 59.03$
