All 4 of your effervescent antacid tablets must be used in the experiment You must measure and record data (time and water temperature) during the experiment using the instruments provided. Stand back… POP! • Taste and taste masking • ODTs When effervescent tablets and water react, carbon dioxide gas is formed. This experimental value will then be compared to the theoretical amount of CO 2 mass generated, found through stoichiometry. (Be sure to use uncoated tablets.) Measure the time required for tablet to fully dissolve. Place the lid on firmly. Usually, these tablets are prepared by compressing the active ingredients with mixture of sodium bicarbonate and organic acids such as citric and tartaric acid. The tablets are shown to help see how the experiment was setup, but the model represents the air bubbles after the tablets fully dissolved. Alka Seltzer is a base, or a molecule that can take up hydrogen ions. Below is the corrected data set. Experiment 2: Tablet broken into 16 pieces f.
