| Abstract: | The stability constants of the silver(I) complexes of five azo dyes have been determined by means of potentiometric equilibrium measurements with silver electrodes in 75% vlv acetone-water solution. Each azo dye molecule was shown to co-ordinate at most three silver ions. The sequence of the stepwise stability constants indicated an effect stabilizing complexes with high silver content. |
