Chem Unit 11 Solutions (Chapter 12)

Target 11-01 Classify mixtures as solutions, suspensions, colloids, electrolytes and nonelectrolytes.

“I can” Statements:

11-01 a: Distinguish between heterogeneous and homogeneous mixtures.

11-01 b: List three different solute-solvent combinations.

11-01 c: Compare the properties of suspensions, colloids, and solutions.

11-01 d: Distinguish between electrolytes and nonelectrolytes.

Target 11-02  Describe the solution process and solution equilibrium including solubility graphs, saturated, unsaturated, and supersaturated solutions.

“I can” Statements:

11-02 a:List and explain three factors that affect the rate at which a solid solute dissolves in a liquid solvent.

11-02 b Explain solution equilibrium, and distinguish among saturated, unsaturated, and supersaturated solutions.

11-02 c. Explain the meaning of “like dissolves like” in terms of polar and nonpolar substances.

Target 11-03 Explain how the rate of solution is affected by variables such as temperature, surface area, pressure, agitation, polarity, enthalpy of solution and solvent/solute ratios.

“I can” Statements:

11-03 a. List the three interactions that contribute to the enthalpy of solution, and explain how they combine to cause dissolution to exothermic or endothermic.

11-03 b. Compare the effects of surface area, pressure, agitation, polarity, enthalpy of solution, solvent/solute ratios, temperature and pressure on the solubility of gasses, liquids, and solids.

Target 11-04 Determine the concentration of solutions including molarity and molality.

“I can” Statements:

11-04 a. Given the mass of solute and volume of solvent, calculate the concentration of a solution.

11-04 b. Given the concentration of a solution, determine the amount of solute in a given amount of solution.

11-04 c. Given the concentration of a solution, determine the amount of solution that contains a given amount of solute.
