Reaction of methanoic and ethanoic acids with CaCO3
If I have a 1 liter aqueous solution that contains 15 mg/L methanoic acid and 15 mg/L ethanoic acid, what amount of calcium carbonate is needed to reduce each acid concentration by at least 50%?

The only other information given is the pKa values for each acid which are 3.75 for methanoic acid and 4.70 for ethanoic acid.
