Units
The Mole Concept
This unit contains interactive lessons that describe the significance, use, and applications of the mole concept.
Stoichiometry
This unit contains interactive lessons related to stoichiometry, a term that refers to the relationship between the amounts of reactants that react together in a chemical reaction and the amounts of products that are formed.
Acids and Bases
This unit contains interactive lessons relevant to acids, bases, and their chemical reactions.
Significant Figures
This unit contains interactive lessons that demonstrate the importance, and use of, significant figures in scientific measurements and calculations.
The History of Atomic Theory
Atom Economy and E-Factor
Chem Lab Days Experiments
These two virtual labs contains interactive lessons that simulates a visit to the University of Waterloo campus.
In this lesson, you will be taken through the procedure to synthesize potassium alum, a compound used in many applications from baking powder to natural deodorants and even as water treatment additive. The written procedure is accompanied by videos and you will have the opportunity to perform relevant stoichiometry calculations to obtain your experimental yield and even view the characterization tests performed to confirm the presence of each ion in potassium alum!
In this lesson, you will be taken through the procedure to synthesize acetaminophen, the active ingredient in Tylenol. The written procedure is accompanied by videos and you will have the opportunity to perform relevant stoichiometry calculations to obtain your experimental yield and even view the melting point of a real acetaminophen sample!
