$17\mathrm{.}88$ Consider the titration of $25\mathrm{.}0mL$ of $1\mathrm{.}0{10}^{-5})$ with $0\mathrm{.}025$MNaOH.

$($a$)$ Sketch the $pH$ titration curve, and label the equivalence point.

$($b$)$ How many milliliters of $0\mathrm{.}025$MNaOH are required to reach the equivalence point?

$($c$)$ Is the $pH$ at the equivalence point greater than, equal to$,$ or less than $7?$

$($d$)$ What is the pH exactly halfway to the equivalence point?
