The extent of a chemical reaction is determined by the amount of reacting materials, or reactants, present in the reacting system. Alka Seltzer, and similar over-the-counter combination antacid and pain relief medications, contain aspirin (acetylsalicylic acid), citric acid, and NaHCO3 as the active ingredients. Also include a graph of the mass% of NaHCO. Place the pre-weighed watch glass reweigh the beaker, its solution, and the watch glass. To determine the grams of CO2, subtract the total mass after place where mass percent is important is in medications.
