Problem
The following skeletal equation represents a redox process that occurs in acidic solution during an electrochemical experiment.
__MnO4−(aq)+__Fe2+(aq)→__Mn2+(aq)+__Fe3+(aq)
Coefficients and, if necessary, electrons are omitted.
(1) Part 1: (a) Balance the atoms other than H and O in each half-reaction.
(2) Part 2: (b) Balance oxygen and hydrogen atoms by adding H2O and H+ as needed for an acidic medium.
(3) Part 3: (c) Balance the charge of each half-reaction by adding electrons, then combine the half-reactions so that electrons cancel.
(4) Part 4: (d) Report the final balanced net ionic equation with integer coefficients and demonstrate explicitly that both mass and charge are conserved.
