Stability constant of palladium, cooper, nickel, zinc and manganese chelates of N-benzoyl-N-p-chlorophenylhydroxylamine

Stabilities of palladium, copper, nickel, zinc and manganese chelates of N‐benzoyl‐N‐p‐chlorophenylhydroxylamide in 70% v/v dioxan‐water mixture have been determined by employing Bjerrum‐Calvin pH titration technique. The titration medium was maintained at a constant ionic strength 0.1 M KCl and at a temperature, 25 ± 0.5° log K, palladium 18.21, copper 17,89, nickel 12.23, zinc 10.27 and manganese 9.57. Die Stabilitätskonstanten von Pd‐, Cu‐, Ni‐, Zn‐ und Mn‐Chelaten mit N‐Benzoyl‐N‐p‐chlorphenylhydroxylamin wurden nach Bjerrum‐Calvin pH‐titrimetrisch (0,1 m KCl; 25 ± 0,5 °C) bestimmt; log K‐Werte siehe “Summary”.
