$pH=$This question has multiple parts. Work all the parts to get the most points.

What is the $pH$ of a solution that is

a prepared by dissolving $5\mathrm{.}30g$ of glycolic acid $(76\mathrm{.}05\frac{g}{m}ol)$ and $11\mathrm{.}57g$ of sodium glycolate

$(98\mathrm{.}03\frac{g}{m}ol)$ in water and diluting to $1\mathrm{.}00L?$ glycolic acid $\{$:$)=1\mathrm{.}47{10}^{-4}$

$pH=$

b $0\mathrm{.}0480M$ in propanoic acid and $0\mathrm{.}0255M$ in sodium propanoate?

$(K_a($ propanoic acid $)=1\mathrm{.}34{10}^{-5})$

$pH=$

C prepared by dissolving $2\mathrm{.}10g$ of chloroacetic acid, $ClC{H}_2\frac{C}{O}OH(94\mathrm{.}49\frac{g}{m}ol)$ in $50\mathrm{.}0mL$ of

$0\mathrm{.}2280$MNaOH and diluting to $450\mathrm{.}0mL?$ chloroacetic acid $\{$:$)=1\mathrm{.}36{10}^{-3}$

$pH=$

d $0\mathrm{.}0120M$ in iodic acid and $0\mathrm{.}0120M$ in sodium iodate? iodic acid $\{$:$)=1\mathrm{.}7{10}^{-1}$

$pH=$
