Chem Unit 11 Solutions (Chapter 12)

Targets:

Chem Target 11-01 I can classify mixtures as solutions, suspensions, colloids, and suspensions, electrolytes and nonelectrolytes.

Chem Target 11-02 I can describe the solution process, solubility and solution equilibrium including saturated, unsaturated and supersaturated solutions.

Chem Target 11-3 I can describe factors such as temperature (enthalpy), pressure, agitation, polarity, and solvent/solute ratios affect the rate of solution.

Chem Target 11-4 I can determine the concentration of solutions including molarity and molality.

Text Objectives:

Distinguish between heterogeneous and homogeneous mixtures

List three different solute-solvent combinations

Compare the properties of suspensions, colloids, and solutions.

Distinguish between electrolytes and non-electrolytes.

List and explain three factors that affect the rate at which a solid solute dissolves in a liquid solvent.

Explain solution equilibrium, and distinguish among saturated, unsaturated, and supersaturated solutions.

Explain the meaning of “like dissolves like” in terms of polar and non-polar substances.

List the three interactions that contribute to the enthalpy of solution, and explain how they combine to cause dissolution to be exothermic or endothermic.

Compare the effects of temperature and pressure on solubility.

Given the mass of solute and volume of solvent, calculate the concentration of a solution.

Given the concentration of a solution, determine the amount of solute in a given amount of solution.

Given the concentration of a solution, determine the amount of solution that contains a given amount of solute.
