You are given a freshly prepared ferrous solution whose Fe2+ concentration is yet to be determined by redox titrimetry. The following chemicals and glasswares are available for you to determine the Fe2+ concentration: Ferrous sulphate solution (unknown), FeSO4(aq) Potassium permanganate solution, KMnO4= 0.02 moldm-3 di-potassium oxalate monohydrate, K2C2O4 .H2O solids Analytical balance Hot plate with magnetic stirring facility Burette (50.00 mL) Pipette (25.00 mL) 3M H2SO4 solution Titration flask How would you determine Fe2+ concentration in ferrous sulphate solution as accurately and precisely as possible. {Hint: Identify the Primary standards, Secondary standards, Precision of the instrument and glasswares.}
