2.4.0 mL of 3.00 M HCl reacts completely with the CaCO3 (active ingredient) in an antacid tablet. The remaining solution (excess HCl) is then titrated with 0.0981 M NaOH to the bromothymol blue endpoint. Write the balanced chemical equation for the reaction of CaCO3 (s) with HCl (aq). If the volume of NaOH delivered at the endpoint is 22.20 mL, determine the amount (in milligrams) of CaCO3 that was contained in the antacid tablet.
