Redox equations

    Is there a way to figure out one side of a redox half equation when the other side is given? ex- Mn04- -> Mn2+

    You generally need to know the oxidation states of the atoms of the compound under consideration, but often then can be figured out if you know the oxidation state of one of the atoms and the total charge on the ion. Oxygen is always -2, for instance, and the halogens are always -1.

    Not really.Oxygen can be 0,+2,-1,-2 and +1.Halogens can have many ON-s,the simplest case is fluorine which ALWAYS -1.
