Kinetic and stoichiometric measurements of the reductions of Ru(NH3)6+3 by Cr+2(aq) (Cl- independent as well as Cl- catalyzed paths) and stoichiometries of the reaction of Ru(NH3)5Cl+2 with Cr+2 are reported. Evidence is presented that the reduced species is in each case a Ru(II) ammine and that the ammine ligands remain in the Ru(II) coordination sphere for reasonable periods of time. The standard oxidation potential of Ru(NH83)6+2 = Ru(NH3)6+3 + e- has been determined as -0.214 v. Further kinetic studies of oxidation of Ru(II) species by ClO4- and Co(III) ammines are reported. Equilibrium quotients for the anation of Ru(NH3)5OH2+3 by Cl-, Br-, and I- have been determined taking advantage of the catalysis of the reactions by Ru(NH3)5OH2+2.
