Module 3 – Case

THERMOCHEMISTRY AND INTRO TO QUANTUM THEORY

Case Assignment

You will complete two virtual lab activities for this Case assignment using the PhET

website provided by the University of Colorado at Boulder.

You must have the most current versions of Java and in order to use this virtual

laboratory!

Solubility of salts

First use this linked handout on Solubility Equilibrium and review the Le Chatelier

Principle to prepare for your Case Part 1 and Part 2.

You will use https://phet.colorado.edu/en/simulation/soluble-salts to examine the solubility of

salts, describe equilibrium of a saturated solution, and consider the effect of

thermodynamic and entropic factors on the solubility product constant (Ksp) for various

solids.

First complete Case 3 Part 1 Salts and Equilibrium

Next complete Case 3 Part 2 Comparing Q and Ksp

Assignment Expectations

Complete each of the activities above, and submit both as Word documents or pdfs to your

Case dropbox.  List your references at the end of each worksheet (refer to the Background

materials and linked resources).
