Aqueous solution of `Ni^(2+)` contains `[Ni(H_(2)O)_(6)]^(2+)` and its magnetic moment is 2.83 B.M. When ammonia is added in it, the predicted change in the magnetic moment of solution is:

Options

A. It will remain same
B. It increases from 2.83 B.M.
C. It decreases from 2.83 B.M.
D. It cannot be predicted theoretically

Answer

A

Explanation

`[Ni(NH_(3))_(6)]^(2+) implies sp^(3)d^(2)`
