Q. The colour exhibited by one of the iron ions in aqueous solutions is pale green. The primary valency and secondary valency respectively in the green complex are
1) 2, 4
2) 2, 6
3) 3, 4
4) 3, 6
Dear Student,
Name of the pale green complex of iron is potassium ferrioxalate K3[Fe(C2O4)3]
Primary valency = 3
Secondary valency = 6
So correct option is 4) 3, 6
