• The mixed-ligand complexes of cadmium with 2,2′-bipyridyl and dicarboxylic acids (tartaric, succinic, maleic, malonic, and malic) were studied polarographically in the 50% dioxane medium. The stability constants of simple systems were calculated by Deford and Hume method, and the values of stability constants of mixed-ligand complexes have been determined by the method of Schaap and McMasters. The overall stability constants have been evaluated with the help of Leden's graphical extrapolation method and the values of β<SUB>11</SUB>, β<SUB>12</SUB> and β<SUB>21</SUB> are (5.24, 5.80, and 8.19) for Cd-bpy-tartarate system (5.62, 6.15, and 8.34) for Cd-bpy-succinate system (5.48, 6.10, and 8.32) for Cd-bpy-maleate system (5.57, 6.15, and 8.37) for Cd-bpy-malonate system, and (5.57, 6.15, and 8.34) for Cd-bpy-malate system.
