Question:medium

Given below are two statements: Statement-I: The percent compositions of $\mathrm{Ni}^{2+}$ and $\mathrm{Ni}^{3+}$ in $\mathrm{Ni}_{0.98}\mathrm{O}$ respectively is 96% and 4%. Statement-II: The fraction of $\mathrm{Fe}^{3+}$ and $\mathrm{Fe}^{2+}$ ions in 1 mole of $\mathrm{Fe}_{0.93}\mathrm{O}$ is 0.14 and 0.79 respectively. Choose the correct option.

Show Hint

For non-stoichiometric oxides, always apply electrical neutrality. The total positive charge must equal the total negative charge contributed by oxide ions.
