Consider the following electrochemical cell:

Al(s) | Al^3+(aq)(0.155 M) || H^(aq)
(0.00233 M), MnO4^-(aq)(0.0377 M), Mn^2+(aq)
(0.0168 M) | C (graphite)
Write a balanced equation for the redox reaction taking place in this cell. i am having trouble with the cathode half reaction.

1 answer

MnO4^- + 8H^+ + 5e ==> 4H2O + Mn^2+
