Lab 18: Alka Seltzer and the Ideal Gas Law
I. Introduction: In this lab the purpose was to measure the reaction between Alka Seltzer and water and to determine the mass of the gas produced. What we did was, first we smashed up an alka seltzer tablet and put it inside a balloon. We then put the balloon over a graduated cylinder full of water and as the two substances combined, CO2 was produced and collected in the balloon. After all the gas had been created we measured the circumference of the balloon. We then emptied the gas and refilled the balloon with water until it had the same circumference. From this we were able to measure the water and find the volume. Through a series of calculations , we were able to conclude that the mass of CO2 was around 1.26 grams in our experiment. II. Data: III. Calculations: (Setup) IV: Analysis Questions: 1. Discuss an area in this lab where experimental error may have occurred. There are many instances where an experimental error may have occurred For exam
