Experiments in General, Organic, and Biological Chemistry |
Students react baking soda and washing soda with hydrochloric acid. After evaporating water, they determine the amount of carbon dioxide released in each reaction and thus they can verify the stoichiometry of each reaction. They also become familiar with the concept of reaction yield.
