The oxidation of Cu(I) in seawater and NaCl solutions has been measured as a function of pH, temperature, ionic strength and the presence of various ions. The strong Cl dependence of the rates has been attributed to the effect of temperature and ionic strength on the oxidation of Cu and CuCl° species. At a fixed Cl concentration, the addition of Mg2- causes the rate to decrease and the addition of HCOo causes the rate to increase. The possible causes of these effects are dicussed. The results are used to derive a rate equation valid for most natural waters from 0 to 50°C, I=0-6 M and pH=6-9.
