When `SCN^(-)` is added to an aqueous solution containing `Fe(NO_(3))_(3)`, the complex ion produced is

A

`[Fe(OH_2)_2(SCN)]^(2+)`

B

`[Fe(OH_2)_5 (SCN)]^(2+)`

C

`[Fe(OH_2)_8(SCN)]^(2+)`

D

`[Fe(OH_2)(SCN)]^(6+)`

Text Solution

Verified by Experts

The correct Answer is:
B
When `SCN^(-)` is added to an aqueous solution containing `Fe(NO_3)_3`, pentahydrated complex is formed. `Fe^(3+) + SCN^(-) + H_2O to [Fe(H_2O)_5SCN]^(2+)`.
