$1.$ Calculate the pOH, pH$,$ and $\%$ionization of a solution formed by mixing $100$ mL $0\mathrm{.}1$ M diethylamine, $($C$2$H$5)2$NH$,$ and $10$ mL $0\mathrm{.}500$ M NaOH.

$($C$2$H$5)2$NH$($aq$)+$ H$2$O$($l$)($C$2$H$5)2$NH$2+($aq$)+$ OH$-($aq$)$ Kb $=6\mathrm{.}9$x${10}^{-4}$

$2.$ Compute for the pH$,$ pOH, and $\%$ionization of $100$ mL $0\mathrm{.}100$ M diethylamine solution and compare these values with those previously computed $($those in the presence of NaOH$).$ Explain the differences or similarities observed.
