Objectives of Solution - Revised 2009

Essential Question: Essential Questions (EQ4): Do and/or how do basic particles interact - Stay same?

Each student will be able to:

1. Be able to explain the differences between solutions, colloids, and suspensions. Be able to explain the properties of a solution including the Tyndal effect.

2. Determine and explain miscibility and dissolving of two subtances using knowledge of IMF including in words and in drawing pictures.[7.1](7.1). [Animated Website of Sodium Chloride dissolving in water].

3. Explain the difference between unsaturated solution, saturated solution (Ksp), saturated solution with solid solute on bottom and be able to identify their location on a solubility curve. Explain what a supersaturated solution is. Specifically, for saturated solution be able to explain how it is a dynamic equilibrium condition [7.3].

4. Identify and explain (using words) the factors that affect the rate of dissolving, i.e., temperature, concentration, and mixing (stirring, powderizing).[7.2](7.3)

5. Calculate concentration in terms of molarity, molality, and solubility.[7.4]. Use molarity to perform solution dilution (i.e. do dilution calculations) and solution stoichiometry.(7.2). Be able to obtain a solubility value from a solubility curve [7.5]. and be able to explain how solubility changes with temperature for both ionic solid and gas solutes.

6. Compare and contrast qualitatively the properties of solutions and pure solvents (called Colligative properties) including Boiling point elevation, Freezing point depression and Rauolt's Law (Rauolt's Law not for 2015-2016 Learners). Also be able to do Colligative Property calculations (No calculations for 2014-2015 Learners).(7.4)
