Chapter 4, Problem 85QP

Calculate the volume in milliliters of a $\text{1}\text{.420 }M\text{ NaOH}$ solution required to titrate the following solutions:

$\begin{array}{l}\left(\text{a}\right)\hfill \\ \text{25}\text{.00 mL of a 2}\text{.430 }M\text{ HCl solution}\hfill \\ \left(\text{b}\right)\hfill \\ \text{25}\text{.00 mL of a 4}\text{.500 }M{\text{ H}}_{\text{2}}{\text{SO}}_{\text{4}}\text{ solution}\hfill \\ \left(\text{c}\right)\hfill \\ \text{25}\text{.00 mL of a 1}\text{.500 }M{\text{ H}}_{\text{3}}{\text{PO}}_{\text{4}}\text{ solution}\hfill \end{array}$
