Questions, please
An Alka-Seltzer tablet consists of NaHCOs (sodium bicarbonate), citric acid (H3C&HsO; citric acid is triprotic), aspirin and other inert ingredients. When dissolved in water, citric acid and NaHCO3 components react as follows: In the first part of the experiment, we will determine the mass of NaHCO in a tablet of Alka Seltzer. To do this, we will use a known mass of a powdered sample of Alka-Seltzer and determine the mass of CO2 gas...

Below is a lab hand out for the questions. All my data for the questions are filled out below in BOLD LETTERING. All the questions I need answered are at the bottom with boxes where to put the answers. Background Alka-Seltzer� is an over-the-counter antacid and pain relief drug. The tablet contains aspirin (acetylsalicylic acid), citric acid, and sodium bicarbonate (NaHCO3). Sodium bicarbonate (NaHCO3) is responsible for the effervescent action of Alka-Seltzer. In this lab we will investigate the reaction...
