- 中文摘要: The oxidation of iodine by ceric sulfate in sulfuric acid solution has been found to be of second-order with respect to iodine and first-order with respect to Ce(IV), by spectrophotometric measurements. CeSO4 +2 was assumed to be the active species of ceric sulfate. The over-all rate constants were found to be k0=2.66×10.. …/M2.Min for the reaction rate, -d[I2]/dt=k0[C3 (IV)][I2]2 in 1.0 M H2So4 and k''=1.12×10.. …/M2.Min for the reaction rate, -d[I2]/dt=k''[CeSO4 2+] [I2]2.
