WebMar 26, 2024 · During titration, one of the chemical compounds will get oxidised at the same time the other reactant will get reduced. In the presence of sulphuric acid KMnO4 is a powerful oxidising agent and it can be used for the estimation of oxalic acid (oxalates). Oxalic acid reacts with the acidic K M n O 4 WebIn my school, there is a redox titration between H2C2O4 being titrand and KMnO4 being titrant. After adding H2SO4 to the acid to give an acidic medium for redox, the whole mixture inside the conical flask is heated up to 80 degree Celsius before titration starts, what is the need of heating? titration Share Improve this question Follow
