The concentration of hydrogen peroxide solution can be determined by
titration with acidified potassium manganate(VII) solution. In this reaction
hydrogen peroxide is oxidised to oxygen gas. A 5.0 cm sample of hydrogen
peroxide solution was added to a volumetric flask and made to 250 cm
of the aqueous solution. A 25.0 cm sample of this solution was acidified
and reacted completely with 24 35 em of 0.0187 mol dm potassium
manganate(VII) solution
(ay Write a balanced equation for the reaction between acidified KMnO
solution and H. O.
(b) Calculate the concentration of the original H, O, solution in mol dm
