Aqueous solution of $Ni^{2+}$ contains $[Ni(H_2O)_6]^{2+}$ and its magnetic moment is $2.83 \, BM$. When ammonia is added to it,comment on the magnetic moment of the solution.

• A
  It will remain same
• B
  It increases from $2.83 \, BM$
• C
  It decreases from $2.83 \, BM$
• D
  It cannot be predicted theoretically
