Chapter 13, Problem 94E

A 25.0-mL sample of an unknown ${\text{HClO}}_{\text{4}}$ solution requires 45.3 mL of 0.101 M NaOH for complete neutralization. What was the concentration of the unknown ${\text{HClO}}_{\text{4}}$ solution? The neutralization reaction is:

${\text{HClO}}_{\text{4}}\left(aq\right)+\text{NaOH}\left(aq\right)\to {\text{H}}_{\text{2}}\text{O}\left(l\right)+{\text{NaClO}}_{\text{4}}\left(aq\right)$
