Solutions and Concentration

Thursday
Goal: Elaborate on nature of solutions.
Finish Vocab discussion.
1.) Solubility Table Temperature: Sodium Chloride, Potassium Nitrate
Make a line graph to compare the two.
2.) Questions.
-What caused somethings that were soluble to become insoluble?
-When did solubility increase? Why? Relate to kinetic theory?
-When something dissolves, does it like water or hate water?
3.) Molarity vocabulary discussion
4.) CALM Work

Tuesday
Goal: Relate nature of solutions to solution calculations.
