e2.6 use stoichiometry to solve problems involving solutions and solubility [AI]
e2.7 determine the concentration of an acid or a base in a solution (e.g., the concentration of acetic acid in vinegar), using the acid–base titration technique [PR, AI]
e2.8 conduct an investigation to determine the concentrations of pollutants in their local treated drinking water, and compare the results to commonly used guidelines and standards (e.g., provincial and federal standards) [PR, AI]
E. Understanding Basic Concepts
By the end of this course, students will:
e3.1 describe the properties of water (e.g., polarity, hydrogen bonding), and explain why these properties make water such a good solvent
e3.2 explain the process of formation for solutions that are produced by dissolving ionic and molecular compounds (e.g., salt, oxygen) in water, and for solutions that are produced by dissolving non-polar solutes in non-polar solvents (e.g., grease in vegetable oil)
e3.3 explain the effects of changes in temperature and pressure on the solubility of solids, liquids, and gases (e.g., explain how a change in tem- perature or atmospheric pressure affects the solubility of oxygen in lake water)
e3.4 identify,usingasolubilitytable,theformation of precipitates in aqueous solutions (e.g., the use of iron or aluminum compounds to precipi- tate and remove phosphorus from wastewater)
e3.5 explaintheArrheniustheoryofacidsandbases
e3.6 explain the difference between strong and weak acids, and between strong and weak bases, in terms of degree of ionization
