100ml of a 0.10M NH3 solution is titrated with a 0.05M HCl solution. pKb for NH3 is 4.75 What is the pH of the NH3 solution before adding HCl? pKb=-log Kb Kb=1.778x10^-5 What is the pH after 100ml of HCl is added? What is the pH after an additional 100ml is added (total HCl v=200ml)? I'm not sure wh...
