Solubility Lab and Dissolved Gases

Today, we completed the solubility lab.  In addition, we observed the affect of increasing temperature on dissolved gases.

HW: Complete the following journal entry (Due Monday) -

1. What is solubility?
2. How does a solution form (three step - solvation and hydration)? What is the role of energy in this process? Draw diagrams to illustrate both endothermic and exothermic processes.
3. How does an increase in temperature affect the solubility of a solid? and a gas? Explain using the Kinetic Molecular Theory.
4. Solubility Lab - summarize the materials, procedure, observations, analyses (solubility curves plotted on a graph) and conclusions.
