A. When a 3.28 g sodium bicarbonate tablet was dissolved in vinegar, 0.68 g of CO2 was produced. Use the stoichiometry NaHCO3(aq) + HC2H3O2(aq) → CO2(g) + H2O(l) + NaC2H3O2(aq) to calculate the amount (moles) of NaHCO3 consumed.
B. Assume all the NaHCO3 consumed originated from the tablet. Calculate the mass of NaHCO3 in the tablet.
C. Based on your answer on B, calculate the mass percent on NaHCO3 contained in the tablet.

The fizz produced when an AlkaSeltzer® tablet is dissolved in water is due to the reaction between sodium bicarbonate, NaHCO3, and a triprotic organic acid, citric acid, H3C6H5O7. The products of this reaction are carbon dioxide gas, water, and sodium citrate. 3 NaHCO3 (aq) + H3C6H5O7 (aq)→ 3 CO2 (g) + 3 H2O(l) + Na3C6H5O7 (aq) In an experiment 1.00 g of sodium bicarbonate and 1.00 g of citric acid are allowed to react. A.Which of the five compounds in...
