A 0.2719g solid sample containing calcium carbonate and other salts (that do not react with acids) is dissolved with 20.00mL of 0.2254 M hydrochloric acid. The resulting solution is then titrated with 0.1041 M sodium hydroxide, and 12.39 mL of the sodium hydroxide solution are needed to reach a phenolphthalein end point.

A. Write the 2 reactions that occur in this analysis

B. What is the weight percentage of calcium carbonate in the sample?
