Metal deficiency defect is shown by

{Fe}_{0 . 93}O

. In the crystal, some

{Fe}^{2 +}

cations are missing and loss of positive charge is compensated by the presence of

{Fe}^{3 +}

ions. The percentage of

{Fe}^{2 +}

ions in the

{Fe}_{0 . 93}O

crystals is____(Nearest integer)

Correct answer

Step-by-step solution

In ${Fe}_{0 . 93}O$ for every $93Fe$ ions $14$ are {Fe}^{+ 3} and \left(93 - 14\right) = 79 $are$ {Fe}^{+ 2} $ions</p><p>$ ∴ % {Fe}^{+ 2} = \dfrac{79}{93} \times 100 = 84 . 9 % $</p><p>$ ∴ $nearest integer$ = 85 %$
