Asolution of KMnO4 is to be standardized by titratign it against As2O3. A 0.1156 g sample of As2O3 requires 27.08 mL of the KMnO4 solution. The reaction is in acidic environment accoridng to MnO4(-)(aq) +As2O3 (s) = H3AsO4 (aq) +Mn(2+ )(aq) a. Balance in acidic B calculate the molarity of the KMnO4 solution.
