MnO_(4)^(-) ions are reduced in acidic conditions to Mn^(2+) ions whereas they are reduced in neutral condition to MnO_(2) . The oxidation of 25 mL of a solution x containing Fe^(2+) ions required in acidic condition 20 mL of a solution y containing MnO_(4) ions. What value of solution y would be required to oxidize 25 mL of solution x containing Fe^(2+) ions in neutral condition ?
