Analysis show that nickel oxide consists of nickel ion with `96%` ions having `d^(8)` configuration and `4%` having `d^(7)` configuration. Which amongst the following best represents the formula of the oxide?A. `Ni_(1.02)O_(1.00)`B. `Ni_(0.96)O_(1.00)`C. `Ni_(0.98)O_(0.98)`D. `Ni_(0.98)O_(1.00)` |

Answer» Correct Answer - D `d^(8)toNi^(2+) " " d^(7)toNi^(3+)` Total charge of nickel. `(0.96xx2)+(0.04xx3)=2.04` No of `O^(2-)` ion`=2.04/2=1.02` Formula of solid`=NiO_(1.02)=Ni_(0.98)O` |
