    Solution Preview

    There is a formula pH = pKa + log(A/HA)

    were Ka is the acid dissociation constant, A and HA are the acid anion concentration and protonated acid concentration, respectively.

    Also if you react sodium bicarbonate and NaOH...

    NaHCO3 + NaOH --> Na2CO3 + ...

    Solution Summary

    This solution is found using the formula pH = pKa + log(A/HA).
