Question

Analysis show that iron oxide consist of Iron ion with 94 % ions having d 6 configuration and 6 % having d 5 configuration. Which amongst the following best represents the formula of the oxide?, F e 0.97 O, F e 1.03 O, F e 0.60 O, F e 0.94 O 0.94

MARKS App · Accepted Answer

d 6 → F e + 2 , d 5 → F e + 3 Total charge of Iron = 0.94 × 2 + 0.06 × 3 = 1.88 + 0.18 = 2.06 Number of O – 2 i o n = 2.06 2 = 1.03 Formula of solid = F e O 1.03 = F e 0.97 O
