MCQ+4 / -12022
Given below are half cell reactions:
\(MnO_4^ - + 8{H^ + } + 5{e^ - } \to M{n^{2 + }} + 4{H_2}O\),
\(E_{M{n^{2 + }}/MnO_4^ - }^o = - 1.510\,V\)
\({1 \over 2}{O_2} + 2{H^ + } + 2{e^ - } \to {H_2}O\)
\(E_{{O_2}/{H_2}O}^o = + 1.223\,V\)
Will the permanganate ion, \(MnO_4^ -\) liberate O2 from water in the presence of an acid?
