Chemical speciation in the system CUI/NH3/Cl- which may be represented by the general equilibrium pCuI(aq)+qNH3(aq)+rCl-(aq) ⇌ Cu p , (NH3)q , Cl r, (p-r)+ ( aq) has been studies by glass electrode potentiometry at 25.0C and an ionic strength of 1.00 M (NaCl04). A number of binary and ternary complexes were detected with formation constants, βpqr:logβ120 = 11 0.077, logβ111 = 8.92±0.045, logβ 112 = 8.82± 0.18 and logβ 121 = 11.33±0.24. The ionization constant of water (pKw) and the protonation constant of ammonia (pKa) obtained by the same procedures were 13.7462±0.0012 and 9.4613±0.0010 at I = 1 (NaClO4), and 13.7165±0.0010 and 9.4521±0.0007 at I = 1 (NaC1) respectively.
