Abstract

The kinetics of the hydrolysis of [(H₂0)₅CrC(CH₃)₂0H]²⁺in the pH range 0.0-5.6 are reported. The results indicate that the hydrolysis reaction is faster for [(H₂0)_5-n(0H)nCrC(CH₃)₂0H]^2-n. Furthermore, the rate of hydrolysis of [(H₂0)₅CrCR1R₂OH]²⁺is accelerated by acetate anions. The mechanistic implications of these results are discussed in detail.
