An antacid tablet from Brand A is broken in half. One of the pieces weighs 0.56g. This piece is stirred with water and 4 drops of phenolphthalein. Two burets are set up. The acid buret contains 0.2063 M hydrochloric acid solution. The base buret contains 0.1008 M sodium hydroxide solution. The initial readings of the burets are: the acid buret 1.43 mL, the base buret 0.85 mL. Acid is added to the titration flask, the mixture is boiled for 2 minutes, cooled, and then titrated with the base solution until the mixture is a faint pink. The final buret readings are: acid buret 28.44 mL. base buret 17.25 mL.
