Balance the redox reaction between oxalate and permanganate in acidic solution that will be used as the basis of titrations in this experiment. Fill in each blank with the appropriate stoichiometric coefficient as a numeral (avoid leading and lagging spaces). The coefficient on permanganate has been provided. C2O4^2-(aq) + Mn2O^- (aq) + H3O+(aq) → Mn^2+ CO2(g) H2O(l)
