Chapter 11.8, Problem 11.65QAP

A solution of 0.204 M NaOH is used to titrate 50.0 mL of a 0.0224 M ${\text{H}}_{\text{3}}{\text{PO}}_{\text{4}}$ solution. What volume, in milliliters, of the NaOH solution s required?

${\text{H}}_{\text{3}}{\text{PO}}_{\text{4}}\left(aq\right)+\text{3NaOH}\left(aq\right)\to {\text{3H}}_{\text{2}}\text{O}\left(l\right)+{\text{Na}}_{\text{3}}{\text{PO}}_{\text{4}}\left(aq\right)$
