Experimentally it was found that a metal oxide has formula M0.98O.Metal M, is present as M2+and M3+ in its oxide. Fraction of the metal which exists as M3+ would be:
5.08 %
7.01 %
4.08 %
6.05 %
As we have learned
Oxidation Number -
Oxidation number denotes the oxidation state of an element in a compound ascertained according to a set of rules formulated on the basis that electron pair in a covalent bond belogs entirely to more electronegative elements.
-
3x + 2 (0.98 -x) = 2
x+ 1.96 = 2
x = 0.04
