Vedclass · Answer

(A) The reaction is: $[Ni(H_2O)_6]^{2+} + 6NH_3 \rightleftarrows [Ni(NH_3)_6]^{2+} + 6H_2O$. In both complexes,$Ni^{2+}$ has a $d^8$ electronic configuration. Both $[Ni(H_2O)_6]^{2+}$ and $[Ni(NH_3)_6]^{2+}$ are octahedral complexes with $sp^3d^2$ hybridization. Both contain $2$ unpaired electrons. Thus,the effective magnetic moment remains $\mu_{eff} = \sqrt{n(n+2)} = \sqrt{2(2+2)} = \sqrt{8} \approx 2.83 \, BM$.

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.
