- Which entering group would you expect to react fastest with the complex trans-Pt(PEt3)2Cl2? A. Cl-B. SCN-C. Br-D. NO2-A 0.15 M aqueous solution of the chloride salt of the complex ion Pt(NH3 )42+ is found to be weakly acidic with a pH of 4.92. This is initially puzzling because the Cl2 ion in water is not acidic and NH3 in water is basic, not acidic.Finally, it is suggested that the Pt(NH3 )42+ ion as a group donates hydrogen ions. Compute the Ka of this acid, assuming that just one hydrogen ion is donated.Hand- draw the structure of the complex below. Predict using the "18 Electron Rule" if the following complex are stable?
