Assessment Strategies Recommended Learning Resources PRESCRIBED LEARNING OUTCOMES It is expected that students will: define solution as a homogeneous mixture classify a solution as a system distinct from a pure solid, liquid, or gas identify the solute and the solvent as the components of a solution describe the causes of molecular polarity categorize various common solvents as polar and non-polar on the basis of observations, make deductions concerning the solubility of polar and non-polar solutes in polar and non-polar solvents use lab observations to describe the relative conductivity of several solutes in aqueous solution summarize the results of a conductivity experiment as to the types of solute that conduct electricity when dissolved in water propose a mechanism that explains the conductivity of soluble salts in water write dissociation or ionization equations for several substances that dissolve to give conducting solutions calculate the molarity of each ion in a salt solution given the molarity of the solution calculate the concentration of ions resulting when two solutions of known concentration and volume are mixed (assuming no reaction) SUGGESTED INSTRUCTIONAL STRATEGIES The majority of chemical reactions involve chemicals dissolved in a medium such as water.
