Ammonium Cerium(iv) Sulfate VS

Ammonium Cerium(iv) Sulphate VS, Ammonium and cerium sulfate; 2(NH₄)₂SO₄,Ce(SO₄)₂,2H₂O = 632.6

For a 0.1m solution Dissolve 65.0 g of ammonium and cerium sulfate in a mixture of 500 mL of water and 30 mL of sulfuric acid. Allow to cool and dilute to 1000.0 mL with water.

Standardisation. Dissolve 0.300 g of ferrous ethylenediammonium sulfate in 50 mL of sulfuric acid (49 g/L H₂SO₄). Titrate with the ammonium and cerium sulfate solution, determining the end-point potentiometrically (2.2.20) or using 0.1 mL of ferroin as indicator.

1 mL of 0.1 M ammonium and cerium sulfate is equivalent to 38.21 mg of Fe(C₂H₁₀N₂)(SO₄)₂,4H₂O.

Dilution. Use sulfuric acid (59 g/L H₂SO₄) while cooling the solution

For a 0.01m solution To 100 mL of 0.1m ammonium cerium(iv) sulfate VS add, while cooling, 30 mL of sulfuric acid and sufficient water to produce 1000 mL.
