%X Chemical speciation in the system CuI/NH3/Cl- which may be represented by the general equilibrium pCuI(aq)+qNH3(aq)+rCl-(aq)&#8596; Cup(NH3)qClr(p-r)+(aq) has been studied by glass electrode potentiometry at 25.0&#176;C and an ionic strength of 1.00 M (NaClO4). A number of binary and ternary complexes were detected with formation constants, &#946;pqr: log&#946;120 = 11.381±0.077, log&#946;111 = 8.920±0.045, log&#946;112 = 8.82±0.18 and log&#946;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 (NaCl) respectively.
