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...
