Results Part A: Reaction Stoichiometry of Sodium Bicarbonate with Acetic Acid.
Enter the results for Part A, based on the masses determined in the lab video for Part A. Although your
data may not be rounded, round the answers for the results below to the appropriate number of
significant figures.

Using the results above, select the reaction that best described the chemical reaction between sodium
bicarbonate and acetic acid.
NaHCO3(s) + HC2H3O2(aq) → 2 CO2(g) + CH3OH(aq) + NaH(aq)
NaHCO3(s) + HC2H3O2(aq) → CO2(g) + H2O(l) + NaC2H3O2(aq)
2 NaHCO3(s) + HC2H3O2(aq) → CO2(g) + Na2CO3(aq) + H2O(l) + 2 CH2O(aq)

Questio
In Part B, suppose some of your reaction mixture splashed out of the beaker when you dropped the
tablets into the acetic acid. How would this affect your measurements? Be as specific as possible.
How would the splashing error affect the amount of CO2 determined, and consequently, would your
final calculated mass of sodium bicarbonate in the tablet be artificially high or artificially low?
