Mass-Based Approach to the Determination of the Henry's Law Constant for CO2 (g) Using a Diet Carbonated Beverage

摘要

In this laboratory experiment, students apply a mass-based approach to determine the Henry's law constant for CO2 using a small bottle of a diet carbonated beverage. The calculations are challenging; therefore, team-based learning is encouraged. Our students reported values of 0.033 +/- 0.003 mol/(L.atm) at room temperature (18-21 degrees C); when surveyed, these students indicated a high degree of enthusiasm and engagement and development of teamwork abilities.
