Alka Seltzer and the Ideal Gas Law Purpose – When Alka Seltzer reacts with water, CO 2 gas is produced. In this lab, you will collect the gas given off from this reaction. Using the mass difference, you will determine the mass lost by the process, and thus the mass of CO 2 produced. You will use the ideal gas law to calculate the number of moles of gas produced, and from this, the molar mass of CO 2 . Materials: Erlenmeyer flask, Alka Seltzer tablets, mortar and pestle, 9-inch round balloon, scoop, thermometer, barometer, scissors Procedure 1. Fill a flask to overflowing with tap water. 2. Obtain 3 Alka Seltzer tablets and crush. 3. Get a large, round balloon and remove the air from it. 4. Place the tablets in the balloon and attach carefully to the flask (balloon hangs to side). 5. Use electrical tape or duct tape to secure the balloon tightly to the flask. 6. Place the balloon upright to start the reaction. 7.
