Artificial seawater $($Salinity$-20)$ was made in a $N_2-$filled glove bag, so there was no reactivity

with atmospheric $C{O}_2.$ Now, consider what happens when the solution is removed from the

glove bag.

A$)$ What is the numerical value of the total alkalinity while the solution was in the

$N_2$ atmosphere and after it equilibrated with atmospheric $C{O}_2?$

B$)$ What chemical species make up the alkalinity before and after?$|$
