2O(X=Cl, Br, I, SCN, and N
3) was studied at 25°C by spectrophotometry. Changes in the rate constant with increase in the ionic strength are described
by the Debye-Hückel and Gosh-Bjerrum equations. The reaction PtdienCl

− was studied by potentiometry and its rate constant was established to depend weakly on variations of the medium.
Key words salt effect - effect of medium - platinum(II) complexes - diethylenetriamine
