## Abstract The mechanism of oxidation of ternary complexes, [Co^II^(nta)(S)(H~2~O)~2~]^3β^ and [Co^II^(nta)(M)(H~2~O)]^3β^ (nta = nitrilotriacetate acid, S = succinate dianion, and M = malonate dianion), by periodate in aqueous medium has been studied spectrophotometrically over the (20.0β40.0) Β±
## Abstract The kinetics of oxidation of [Cr^III^(Dpc)(Asp)(H~2~O)~2~] (Dpc = dipicolinic acid and Asp = DLβaspartic acid) by __N__βbromosuccinimide (NBS) in aqueous solution have been found to obey the equation: equation image where __k__~2~ is the rate constant for the electron transfer process
In aqueous solutions, [Cr(en)3] 3+ aquates to [Cr(en)z-(H20)2] 3 Β§ A kinetic study of the oxidation of [Cr(en)3] 3+ by N-bromosuccinimide (NBS)in aqueous solutions and water-alcohol solvent mixtures was performed. The reaction is first order with respect to both total [Cr m] and [NBS]. The rate is i
