An equal volume of reducing agent is titrated separately with 1 M `KMnO_4` in acidic, neutral and alkaline media, the volumes of `KMnO_4` required are 20 mL in acid, 33.4 mL in neutral, and 100 mL in alkaline media. Find the oxidation state of Mn in each reduction product. Give balanced equation for all the three half reaction.Find the volume of `1 M K_2Cr_2O_7` consumed when the same volume of reducing agent is titrated in acidic medium.
