Abstract

The kinetics formation of labile complex Ag(I) tetra(p-carboxy-phenyl)porphyrin (TCPP) was investigated at 25 ºC and I = 0.1 M (NaNO₃). By spectrophotometric titration, the composition ratio of the complex was established to be 2:1 (Ag:H₂TCPP). The equilibrium constant (K) was found to be log 10^-6.53. Binding of the first Ag(I) was found to be rate determining step with rate constant, k₁ = 4.67 × 10². A plausible mechanism is discussed.
