Electron transfer reaction of butane -1,3-diol and cr(vi) in aqueous acidic medium

Abstract

Kinetic and mechanistic studies of electron transfer reaction of butane-1,3-diol and Cr(VI) ion in aqueous acidic medium have been carried out in aqueous medium at 271°C, I = 1.0 mol dm^-3 (NaCl), [H ⁺] = 0.5mol dm^-3 (HCl). The reaction was inhibited by added anions and showed negative salt effect. Spectroscopic investigations confirmed that precursor complex formation did not precede the electron transfer step. Interpretation of these observations suggest that the reactions most likely occur by the outersphere mechanism
