    Consider the oxidation of OCS by bromine to sulfate ion and carbonate ion in strong basic solution. What is the ratio of hydroxide ion to product bromide ion?

    1) 2:1
    2) 1:1
    3) 3:2
    4) 8:1

    How would you do this?

    This is what I had in mind:

    OCS - oxidized.
    Br2 - oxidizing agent (reduced).
    We have both reduction and oxidation in one reaction so no electrons needed - i.e. this aint no half reaction.
