A series of collaborative learning activities and accompanying text that develop chemical equilibrium, including acid-base chemistry, formation of water-soluble complexes, and solubility are provided. These activities are intended to be done in class by students working in groups, but can be modified for use as out-of-class exercises. Learning objectives, an instructorâ€™s manual, and out-of-class problems are…

Students examine solubility equilibria including the influence of pH and complexation of the metal species on solubility. A text that accompanies the worksheet and explains the answers to the questions is also available.

Students examine EDTA complexes and the influence of pH and other metal ions on complexation.

Students explore basic concepts of chemical equilibrium calculations when completing this activity.

Students explore calculating the pH of weak acids and bases, buffers and neutralization reactions. A text to accompany the exercise is also provided.

Students explore basic concepts of chemical equilibrium calculations when completing this activity.

Students explore various aspects of solubility equilibria calculations when completing this activity.

Students examine EDTA complexes including EDTA titrations when completing this activity.

Students will learn to:
Recall basic calculations and definitions about acid-base chemistry.
Interpret the pH scale and use Kw to draw relationships between [H+] and [OHâ€“].
Write reactions represented by Ka and Kb for monoprotic acids.…
