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?
Text Solution
Verified by ExpertsThe correct answer is:
A
Total charge of Iron
= (0.94 x 2) + (0.06 x 3) = 1.88 + 0.18 = 2.06
Number of O -2 ion = 
= 1.03
Formula of solid = FeO 1.03 = Fe 0.97 O
