Description
This week’s laboratory assignment is an extension of the concepts we learned about solubility and thermochemistry. The general rule of thumb for the dissolving of chemical compounds in water is that they will readily release heat during the process. Though, there are some compounds like potassium chlorate that respond endothermically during the dissolution process. Even more interesting is that some compounds like cerium(III) sulfate have a higher solubility at lower temperatures. Your initial post to the forum should be in response to the following:
Discuss the relationship between solubility and temperature.
Here are some suggestions of topics on which to elaborate upon in your explanations:
Give real-world examples of the effect of heat on solubility.
Rationalize the relationship (if any) between endothermic/exothermic reactions and solubility.
Discuss the dependence of solubility on temperature.
It’s a class discuss. Please don’t make it too formal.
