Abstract
Stabilities of palladium, copper, nickel, zinc, and manganese chelates of 3-hydroxy-3-phenyl-1-p-chlorophenyltriazene have been determined in 70% v/v dioxan-water mixturre by employing Bjerrum-Calvin pH titration technique. The titration medium was maintained at a constant ionic strength (0.1 m, potassium chloride) and at a temperature, 25±0.5°C. Log K, palladium 20.95, copper 20.65, nickel 14.58, zinc 13.53, and manganese 10.50.
