Which of the following is incorrect for KMnO4 to be used as an oxidising agent? (a) HCl cannot be used because some KMnO4 is consumed in the reaction. (b) Nitric acid is not used for the above purpose because it itself acts as a self oxidising agent and will react with the reducing agent. (c) The equivalent weight of KMnO4 in basic medium is 158. (d) The number of electrons involved in oxidation of KMnO4 in acidic medium is 3.
