The stability constants of ethyl xanthate complexes of cadmium(II), zinc(II), nickel(II), and cobalt(II) were determined spectrophotometrically in aqueous solutions. Complexes with the 1 : 1 composition, M(EX)+, were found in all cases; the stability constants of these metal complexes were calculated to be 1.2×104, 5.2×10, 4.4×10, and 1.1×10 for Cd(EX)+, Zn(EX)+, Ni(EX)+, and Co(EX)+ respectively at an ionic strength of 1.0 and at 25°C. These values were then compared with the stability constants of other metal complexes.
