    Hydrated iron(II) sulphate crystals, FeSO4.H2O are dissolved in H2SO4 and made up to 250 cm3 in a volumetric flask with distilled water.

    Some of the solution of iron(II) sulphate is pippeted into a conical flask and a bit of H2SO4 solution is added.

    The acidified Fe2+ solution is titrated with potassium permanganate, KMnO4.

    Using the above description write a balanced equation.

    im not sure, but i think its that 'standard' redox reaction with the ions?

    5Fe2+ + MnO4- + 8H+ -----> 5Fe3+ + Mn2+ +4H20

    Great, thats what I got right for the ionic one, but what about the basic form of the equation, non ionic version.

    10FeSO4 + 2KMnO4 + 8H2SO4 -> 5Fe2(SO4)3 + K2SO4 + 2MnSO4 + 8H2O
