The concentration of a potassium permanganate (KMNO4) solution is determined by titration with KI(aq) in the presence of excess H2SO4. A balanced chemical equation for the reaction is given below.. 2 KMNO4 + 10 KI + 8 H2SO4 6 K2SO4 + 2 MNSO4 + 5 12 +8 H20 It requires 21.4 mL of 1.62 mol L-1 KI(aq) to completley titrate 40.6 mL of KMNO4(aq). What is the molar concentration of the KMNO4 solution? 0.854 mol L-1 2.56 mol L-1 0.171 mol L-1 8.54 mol L- 0.285 mol L-1
