Chapter 12: Solutions

Mixtures

The Mixtures Lab – interactive activity in which you separate mixtures based on properties of the substances in each mixture.

(Main Idea: Solutions are homogeneous mixtures.)

Solutions

Salts & Solubility –check out the solubility of table salt and other salts in water.  Design
and dissolve your own salt!

(Main Idea: Solubility is a measure of how well one substance dissolves in another.)

Concentration of Solutions

Moles, Molarity, and Molality – explanation of molarity (moles per liter of solution) and molality (moles of solute per kilogram of solvent).

http://library.thinkquest.org/C004970/background/moles.htm

(Main Idea: Molarity is moles of solute per liter of solution; Molality is moles of solute per kilogram of solvent.)

Molarity and Molality – video demonstration of the concepts of molarity and molality.
