Question

Analysis show that nickel oxide consists of nickel ion with 96% ions having d8 configuration and 4% having of d7 configuration. Which amongst the following best represents the formula of the oxide. (A) Ni1.02O1.00 (B) Ni0.96O1.00 (C) Ni0.98O0.98 (D) Ni0.98O1.00

Tardigrade Admin · Accepted Answer

d8 arrow Ni+ 2, d7 arrow Ni+ 3 Total charge of nickel (0.96 × 2)+(0.04 × 3)=2.04 Number of O- 2 ion =(2.04/2)=1.02 Formula of solid =NiO1.02=Ni0.98O1.00

Q. Analysis show that nickel oxide consists of nickel ion with 96% ions having $d^{8}$ configuration and 4% having of $d^{7}$ configuration. Which amongst the following best represents the formula of the oxide.

$N i_{1.02} O_{1.00}$

$N i_{0.96} O_{1.00}$

$N i_{0.98} O_{0.98}$

$N i_{0.98} O_{1.00}$

$d^{8} \to N i^{+ 2}, d^{7} \to N i^{+ 3}$

Total charge of nickel

$(0.96 \times 2) + (0.04 \times 3) = 2.04$

Number of $O^{- 2}$ ion $= \frac{2.04}{2} = 1.02$

Formula of solid $= N i O_{1.02} = N i_{0.98} O_{1.00}$
