Reaction between NaHCO3 and HCl:
Possible Problems: Errors most likely resulted from the time we left the dish on the hot plate and how much acid we used.

Lab 10: Mole-Mass Relationships Lab
Summary: The purpose of this lab was to better understand the mole-mass relationship in a chemical reaction and the interpretation of a balanced chemical equation through a chemical reaction involving sodium hydrogen carbonate and hydrochloric acid. We used about 2 grams of NaHCO3 and a large source of HCl and slowly added the latter into the former until the reaction had stopped. We then heated the mixture on a hot plate until all that was left was salt NaCl from the three products NaCl, CO2, and H2O. Next, we compared this yield to a theoretical yield calculated through stoichiometry. Finally, we took both yields to calculate the percent yield.
