Abstract
The kinetics of electron transfer between chromium(VI) and H3PO3, yiel ding chromium(III), have been investigated in HClO4 and H2SO4 media by visible spectrophotometry. The rate of reaction increased with increa sing [H2SO4] and [HClO4]. A rate law based on ester formation precedin g the electron transfer has been established and a possible mechanism has been proposed. The mechanism and the derived rate law are consiste nt with the observed kinetics.
