In each case, the half-equation for the manganate (VII) ions in acidic solution is: MnO−4 + 8H+ + 5e− → Mn2+ + 4H2O M n O 4 − + 8 H + + 5 e − → M n 2 + + 4 H 2 O. These equations can be combined to give you an overall ionic equation for each possible reaction. That, of course, also gives you the reacting proportions.
