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.

Question

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.
