A is a solution containing 1.58g of KMnO4 per dm³ of solution. B is a solution of 10.0g of FeSO4.X1 () in 1dm³. Put A into the burette and pipette 25.0cm³ of B into a conical flask, add 10.0cm³ of dilute H2S(aq) and titrate with A. Repeat the titration to obtain concordant titre values.
Tabulate your burette readings and calculate the average volume of A used.
The equation of the reactions is: MnO4 (aq)+5Fe2+(aq)+8H+(aq) → Mn2+(aq) +5Fe3+(aq) + 4H2O(1)
From your results and information provided, calculate the:
(i) Concentration of A in mol/dm³
(ii) Concentration of B in mol/dm³ (iii) Concentration of FeSO4 in B in g/dm³
