| Abstract: | Polarographic measurements on the system Cd-thiosalicylic acid (TSA) reveal the formation of a complex, 1:2:: metal: ligand (ammonia buffer pH 9·1,µ=0·2 M, 50% alcoholic medium), dissociation constant of the complex being 6·3 × 10?8 at 30° C. Potentiometric titrations confirmed this stoichiometry, stepwise stability constants, logk 1 and logk 2 being 7·85 and 8·10 respectively. The complex has also been isolated and studied in solid state. |
