Problem

The following skeletal equation represents a redox process that occurs in acidic solution during an electrochemical experiment.

\_\_ \text{MnO}_{4}^{-}(\text{aq}) + \_\_ \text{Fe}^{2+}(\text{aq}) \to \_\_ \text{Mn}^{2+}(\text{aq}) + \_\_ \text{Fe}^{3+}(\text{aq})

Coefficients and, if necessary, electrons are omitted. a. Part 1: (a) Balance the atoms other than H and O in each half-reaction. b. Part 2: (b) Balance oxygen and hydrogen atoms by adding

H_{2}O

and

H^{+}

as needed for an acidic medium. c. Part 3: (c) Balance the charge of each half-reaction by adding electrons, then combine the half-reactions so that electrons cancel. d. Part 4: (d) Report the final balanced net ionic equation with integer coefficients and demonstrate explicitly that both mass and charge are conserved.
