Abstract:
The feasibility of using the mole-ratio method for study of the formation and stability constant of sulfosalicylic acid-copper(Ⅱ) complex was explored. The experimental result revealed that the chelate-to-copper ratio was 1:1 at pH = 5, and its absolute stability constant was found to be lgK = 9.63, which was close to the value 9.52 from the handbook.
Key words: Mole ratio method, Sulfosalicylic acid-copper(Ⅱ) complex, Stability constant
