Chapter 17, Problem 100AP

A volume of $\text{25}\text{.0 mL of 0}\text{.100 }M\text{ HCl}$ is titrated against a $\text{0}\text{.100 }M{\text{ CH}}_{\text{3}}{\text{NH}}_{\text{2}}$ solution added to it from a burette. Calculate the pH values of the solution after (a) 10.0 mL of ${\text{CH}}_{\text{3}}{\text{NH}}_{\text{2}}$ solution has been added, (b) 25.0 mL of ${\text{CH}}_{\text{3}}{\text{NH}}_{\text{2}}$ solution has been added, (c) 35.0 mL of ${\text{CH}}_{\text{3}}{\text{NH}}_{\text{2}}$ solution has been added.
