✦ Synopsis

Silver(1) catalyzed oxidation of aspartic acid by cerium(1V) was studied in acid perchlorate medium. The stoichiometry of the reaction is represented by the eq. (i)

Dimeric cerium(IV) species has been indicated and employed in calculations of monomeric cerium(IV) species concentrations. The reaction is second-order and uncatalyzed reaction also simultaneously occurs along with the silver(1) catalyzed reaction conforming to the rate law (ii) (ii)

where k is an observed second-order rate constant. A probable reaction mechanism is suggested.

The kinetics of oxidation of ethanol by cerium(1V) in presence of ruthenium(II1) (in the order of mol dm-3) in aqueous sulfuric acid media have been followed at different temperatures (25-40°C). The rate of disappearance of cerium(1V) in the title reaction increases sharply with increasing [CzH50H]
