Kinetics of aquation and anation reactions of [RuCl4(H2O)2]- (1), [RuCl3(H2O)3] (2), [RuCl2(H2O)4]+ (3), and [RuCl(H2O)5]2+ (4) species were studied spectrophotometrically at 25°C. The studies reported here include the effect of initial concentration of these species, the hydrogen ion concentration (0.1-1 M), and potassium chloride concentration (0.01-1 M) on aquation and anation rates. Species 1 exists in a protonated form 1a with a lower aquation rate than 1. An acid-catalyzed induced stability for 2 and 4 is responsible for their lowered rates of decay with decreasing pH. Probable mechanisms for all the conversion steps are proposed and the corresponding rate constants computed. With the help of the data obtained, it is concluded that species 2 is the stable product in 10 mM ruthenium(III) chloride in 1 M HCl stock solution.
