Stoichiometry
Solubility, Stoichiometry and Non-stoichiometry
Joseph Lomax | Mon, 01/24/2022 - 19:40
The unspoken word of chemistry: Non-stoichiometric. Stoichiometry and non-stoichiometry are concepts that combine to make a solution that does not have to be difficult to understand.
Food Dyes as Acid-Base Indicators
Tom Kuntzleman | Sun, 11/28/2021 - 10:51
Natural food dyes are being sold online and in stores that can be used as acid-base indicators. These dyes open up a host of possibilities for at-home and in-class. For example, these food dyes can be used as indicators in the quantitative titration of the Mg(OH)2 in milk of magnesia.
Does Alka-Seltzer Tell the Truth? A lab activity with a video pre-lab assigment
Josh Kenney | Mon, 11/15/2021 - 08:55
The lab activity shared here is a simple experiment where students use stoichiometric principles to experimentally determine the amount of sodium bicarbonate in an Alka-Seltzer tablet. Novice students tend to find stoichiometric calculations difficult, so practicing the calculations on a pre-lab assignment boosts their confidence and ultimately leads to more successful labs. The Asynchronous Video Pre-Lab Assignment shared here demonstrates the procedure and the calculations required in the experiment.
The Golden Drain -- A Stoichiometry Case Study
Josh Kenney | Sun, 06/20/2021 - 08:55
The Golden Drain is a case study developed by Sharma and Wolfgang where students work to uncover a company’s lost revenue due to the error of a new employee.
How much carbon dioxide is produced from a gallon of gasoline?
Thomas Cox | Fri, 04/02/2021 - 22:30
This classroom activity challenges students to figure out the volume of gaseous carbon dioxide emitted from the combustion of 1 gallon of gasoline fuel.
Stoichiometry - A Free Virtual Chemistry Lab Activity
Josh Kenney | Tue, 12/15/2020 - 09:38
In this virtual activity, a video introduces stoichiometry and guides students to think conceptually using a simple baking analogy. Afterward, stoichiometry calculations connect to the analogy, that are then reinforced with a simple experiment. Finally, students explore a PhET simulation to deepen their knowledge.
AP Chemistry Stoichiometry and Reactions Lessons
Kristen Drury | Sun, 09/29/2019 - 15:54
The first unit in my sequence for AP Chemistry covers stoichiometry and reactions. The new AP Chemistry Course and Exam Description has identified Learning Objectives which need to be taught and practiced to ensure students perform well on the AP Chemistry Exam. I will identify and describe activities I use to teach students some of the Learning Objectives that I tie into this unit.
Solution to Chemical Mystery #14: Loves Me...Loves Me Not

Did you figure out how the experiment in Chemical Mystery #14 was performed? The solution is presented here!
Review Lab - Better than a Worksheet
Chad Husting | Tue, 01/01/2019 - 07:20
It can be difficult to engage students in reviewing for semester exams by using worksheets or practicing problems on the whiteboard. If you are looking to change up your review plans, you might consider using a lab activity that provides opportunity to revisit many of the topics that need to be covered.
