Vedclass · Answer

(A) The oxidising ability of an anion depends on the oxidation state of the central metal atom. Higher oxidation state of the central atom leads to higher oxidising power.Calculating the oxidation states:$Ti$ in $TiO_{4}^{4-}$: $x + 4(-2) = -4 \implies x = +4$$V$ in $VO_{4}^{3-}$: $x + 4(-2) = -3 \implies x = +5$$Cr$ in $CrO_{4}^{2-}$: $x + 4(-2) = -2 \implies x = +6$$Mn$ in $MnO_{4}^{-}$: $x + 4(-2) = -1 \implies x = +7$The order of oxidation states is $+4 Therefore,the order of oxidising ability is $TiO_{4}^{4-} < VO_{4}^{3-} < CrO_{4}^{2-} < MnO_{4}^{-}$.

The oxidising ability of the given anions follows the order:
