Abstract

The cobalt(II) perchlorate-water system in acetone has been studied in order to investigate the exchange between water and acetone in the coordination sphere of the metal. Concentration quotients at equilibrium were determined by spectrophotometric measurements in the visible region at four different temperatures. NMR measurements reveal that coordination to cobalt is dominated by water molecules even in the presence of large excess of acetone. Little variation of the equilibrium concentration quotients with temperature is in agreement with low enthalpy variation in the water-acetone exchange. This behaviour agrees with the very close DNSbCl5 values of the two solvents.
