ANALYTICA CHIhIICA ACTA 505 VOLUMETRIC STUDIES IN OXIDATION-REDUCTION REACTIONS VIII. OXIDATION WITH CERIC SULPHATE FERROUS ETHYLENEDIAhIINE: SULPHATE &IETHOD The salts of quadrivalent ccrium arc the most vcrsatik of the strong oxidizing agents, which may be used as standard solutions. CARAW,\Y AND OEWER~ showed that fcrrolls ct~lyIellcdi~trnine sulphatc, FcSO,, (CH,.NH,),S0,.4H,O, reacted stoichiometrically with ccric sulphatc which is commonly employed in oxidimctric titrations.

In acid medium ceric sulphatc reacts with ferrous ammonium sulphatc, cuprous chloride, potassium thiocyanatc, sodium thiosulpllatc, sodium nitrite, hydrogen peroxide, sodium oxaiate, hydroquinone and pyruvic acid in accordance with the equations : C(yl-4 4..
