Your Turn $3$

Consider a $750\mathrm{.}0mL$ buffer made by

mixing $0\mathrm{.}440molHC{O}_3^{-}$and $0\mathrm{.}100$mol of

$H_{2}C{O}_3.$ The $pH$ of the buffer is $7\mathrm{.}00.$ What

will be the $pH$ if $0\mathrm{.}001$mol of NaOH is

added to this buffer? Answer $=7\mathrm{.}01$

Addition of a strong base:

$????$longrightarrow $????$

$1$:$1$ reaction mol ratio $???$

depleted and produced $???$
