Aqueous solution of \( \mathrm{Ni}^{2+} \) contains \( \left[\mathrm{Ni}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{2+} \) and its magnetic moment is \( 2.83 \mathrm{BM} \). When
\( P \) ammonia is added in it, comment on the magnetic moment of solution :
(a) It will remain same
W.
(b) It increases from \( 2.83 \mathrm{BM} \).
(c) It decreases from \( 2.83 \mathrm{BM} \).
(d) It cannot be predicted theoretically
