Abstract:

The kinetics of the CrVI-AsIII reaction have been investigated in H2PO4--HPO4 buffers. Complex kinetics have been obtained. The rate law found is first order in total CrVI and AsIII with a complex dependence upon buffer composition. The data point to the reaction proceeding via two activated complexes, H2PO4- . HCrO4- . AsIII and HPO4- . HCrO4- . AsIII.
