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.
The solution shows how calculate the amount of calcium carbonate that will react with a mixture of ethanoic and methanoic acids.
