QUESTION B3 (a) In a redox titration, potassium permanganate, KMnO4, was standardized using 19.60 g/L FeSO4(NH4)804.6H120 (molar mass = 392.21 g/mol) standard solution. A 20.00 mL of the standard solution, acidified with H2SO4 was put in a conical flask and titrated against KMnO4 solution. The titre volume 15,50 mL of KMnO4 solution was required to reach the end-point. The unbalanced titration equation is: Fe2+ (aq) + Mnoj (aq) + H+ (aq) - Fe3+ (aq) + Mn2+ (aq) + H20 12 Marks] (i) Calculate the molarity of the standard solution [5 marks] Balance the above redox equation by the ion-electron method.​
