    so theres this equation:

    IO3- + 3HSO3 ---> I- + 3HSO4-

    iodate ions to iodide ions

    sulphur is changing from +5 oxidation state to +6

    and iodine from +5 to -1

    the question is: the equation shows that 1 mole of iodate ions reacts with 3 moles of hydrogensulphite ions (HSO3) show that the oxidation states agree with the ratio.

    help anyone?!

    You have the oxidation state of hydrogen sulphite ions wrong...

    EDIT: sorry I'll rephase that...

    You have the oxidation state of sulphur in hydrogen sulphite ions wrong...

    there was a miss print in the question as it should of been HSO3- the minus side wasnt printed!
