QUESTION 7 The weak base ammonia, NH3 (MM = 17.03 g mol) was titrated against a solution of HCI (MM = 36.46 g mol). If 18.77 mL of 0.0640 M HCI was required to fully neutralize 20.00 mL of the base solution () What was the initial [NH3]? (1 pt) (1) What is initial pH? (1 pt) () What is the pH after 10.00 mL of acid was added? (1.5 pts) (iv) Calculate the pH at the equivalence point. (1.5 pts)
