water. The extent of competition afforded by the other anions Cl−, Br−, I−, and NO−3 is similarly accommodated, the least solvated NO−3 ion being the best competitor. Competition by the neutral competitor NH3 (at the 1 M level) is shown to be negligible for both a 2+ and 3+ reactant. Finally, acetate ion (1 M) competition has been determined for the base hydrolysis of [(NH3)5CoX]n+, using seven different
