Please with following question!

11. 25.0 ml of a 0.100 M trimethylamine (CH3)3N (a base like ammonia) Kb = 6.3×10-, are
transferred in an Erlenmeyer flask and titrated with 0.100 M of HCl. Predict pH, pOH,
concentration of trimethylamine, concentration of the conjugated acid (CH3)3NH", and
concentration of HCl in the Erlenmeyer flask when:
(a) 0 mL of HCl solution are added to the Erlenmeyer flask
(a) 12.5 mL of HCl solution are added to the Erlenmeyer flask
(c) 25 mL of HCl solution are added to the Erlenmeyer flask
(d) 30 mL of HCI solution are added to the Erlenmeyer flask
(e) Based on the information from points a-d, draw the expected titration curve (pH vs
volume of HCl (ml))
