The Kinetics formation of labile Complex
Ag (I) tetra (pcarboxyphenyl) porphyrin, was investigated at 25oC
and I0.1M (NaNO3). By spectrophotometric titration, the
composition ratio of the complex was established to be 21
(Ag H2TCPP). The equilibrium constant, K, was found to be
log 106.53. 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. We discus theoretically why Ag(I)2TCPP is
unstable.
