Question

Ferrous ion changes to X ion on reacting with acidified hydrogen peroxide. The number of d-electrons present in X and its magnetic moment (in BM) are respectively

MARKS Content Team · Accepted Answer

Correct answer: (B) 5 and 5.92. Ferrous ion (Fe^(2+)) changes to ferric ion Fe^(3+) on reacting with acidified H_2O_2 as. 2Fe^(2+)+H_2O_2+2H^(+)⟶2Fe^(3+)+2H_2O Electronic configuration of Fe^(3+ )= 1s^22s^22p^63s^23p^63d^5 Number of d-electrons = 5 Magnetic moment = √(n(n+2)) = √(5(5+2)) = 5.92 BM
