a 25.0cm3 sample of this solution was acidified and titrated with 0.100 mol dm-3 potassium manganate (VII) solution. 20.0cm3 of this potassium manganate(VII) solution was required to react fully with ethanedioate ions, C2O4 2-, present in the sample.
the MnO 4- ions in the potassium manganate (VII) oxidise the ethanedioate ions.
Complete and balance the ionic equation for the reaction between the manganate (VII) ions and the ethanedioate ions
2MnO 4- + 5C2O4 2- + ...... H + ----> ......(aq) + 10CO2 + ..... H2O
