    Calculate the oxidation state of metal ion in (i) \[{{[Ag{{(CN)}_{2}}]}^{-}}\,\]         (ii) \[[Ni{{(CO)}_{4}}]\]          (iii) \[{{[Fe{{(CN)}_{6}}]}^{3-}}\]

    Answer:

                    (i) \[{{[Ag{{(CN)}_{2}}]}^{-}}\,\] : \[x+2(-1)=-1\] or \[x=+1\]                 (ii) \[[Ni{{(CO)}_{4}}]\]                  : \[x+4(0)=0\] or \[x=0\] (iii) \[{{[Fe{{(CN)}_{6}}]}^{3-}}\]                : \[x+6(-1)\,=-3\] or \[x=+3\]
