Try this Free Chemistry Lab to teach Reaction Stoichiometry. It is a must-do for High School Chemistry students, giving concrete practice in real applications of Stoichiometry as well as valuable lab experience so important for college preparation. It is an easy set-up whether you teach one chemistry class or five in a day.
The familiar Baking Soda and Hydrochloric reaction is treated quantitatively in this classic Chemistry lab using gravimetric analysis. Variations on this activity are widely available, but my years of experience performing it with students of all abilities has given me the advantage of anticipating many of their questions in this version. A sketch of the set-up allows students to visualize the lab ahead of time so they get busy right away. If you like my style of simple wet chemistry, perhaps you will try some of my other labs.
The student procedure fits on both sides of one sheet of paper. It can be used with a student-generated lab write-up, but there is room to fill in the blanks if you prefer. Teacher’s Notes and Answer Key are provided to help with set-up and answers to problems.
