Question

Consider the titration of 100.0 mL of 0.200 M CH3NH2 by 0.100 M HCI. For each volume of HCI added, decide which of the components is a major species after the HCl has reacted completely. Kb for CH3NH2 = 4.4 x 10^-4. 0.00 mL HCI added no: H^+ yes: H2O no: Cl^- yes: CH3NH2 no: CH3NH3^+ HINT: Because no HCl has been added, this solution only contains a weak base and water. See text for discussion of weak base-strong acid titrations. You are correct. Your receipt no. is 164- 3479 50.00 mL HCI added no: H^+ yes: H2O yes: Cl^- yes: CH3NH2 yes: CH3NH3^+ HINT: Assume the added strong acid neutralizes (reacts completely with) the weak base present.
