The \(E^\circ\) value for the \(Mn^{3+}/Mn^{2+}\) couple is more positive than that of \(Cr^{3+}/Cr^{2+}\) or \(Fe^{3+}/Fe^{2+}\) due to change of

The stability of Cu\(^{2+}\) is more than Cu\(^+\) salts in aqueous solution due to -

A. All the transition metals except scandium form MO oxides which are ionic.

B. The highest oxidation number corresponding to the group number in transition metal oxides is attained in Sc\(_2\)O\(_3\) to Mn\(_2\)O\(_7\).

C. Basic character increases from V\(_2\)O\(_3\) to V\(_2\)O\(_4\) to V\(_2\)O\(_5\).

D. V\(_2\)O\(_4\) dissolves in acids to give VO\(_4^{3-}\) salts.

E. CrO is basic but Cr\(_2\)O\(_3\) is amphoteric.
