    Balance the following equations by the half-cell method. Show both half-cell reactions and identify them as oxidation or reduction.

    a) SO32- + MnO4- + H+ --> Mn2+ + SO42- + H2O(l)

    b) Cl2(g) + OH- --> Cl- + ClO3- + H2O(l)

    c) SO42- + I- + H+ --> S2- + I2(s) + H2O(l)

    See attached file for full problem description.
