    I have a question regarding redox reactions
    It is a AS level question and what I don't get is that I don't have a reduction reaction for the reaction to work no matter what I do.
    MnO- 4 + H2SO4 ------------------ Mn+2 + SO-2 4
    If you can get what I am saying

    Don't you have the data sheet where there are a lot of redox reactions mentioned and listed according to their EV values?

    Anyway, you lack the water molecules here.



    You can add the SO4^2- ions if you want, but this is the ionic equation for this redox reaction of MnO4
