Question

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

MARKS App · Accepted Answer

d 8 → N i + 2 , d 7 → N i + 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 = N i O 1.02 = N i 0.98 O 1.00
