9) A 50.0 mL of a 0.100 M ammonia (NH,) solution is titrated with 0.150 M HCI. The k of ammonia is 5.68 X 10". The pK, of ammonia is 9.25. These questions are challenging so this is very similar to the one online but the answers will a be a little different. a) What is the initial pH of the solution? b) A 50.0 mL of a 0.100 M ammonia (NH,) solution is titrated with 0.150 M HCI. What is the pH when 15.0 mL of HCl is added? c) Calculate the pH at the equivalence point.
