  7. Overarching Question: Describe water as a universal solvent. Identify common contaminants in water (sourcing at least one acid, one base, one ion). Explain their origin, their removal, and their environmental impacts.

  9. Activity: Trivia Board Games

  10. Common Misconceptions • Students often do not realize that gases dissolve better in cold water as opposed to hot. They expect all things to dissolve better as the temperature is increased. • Stirring a solute-solvent mixture or increasing the surface area of the solute will NOT increase its solubility in a solution.

  11. Common Misconceptions • Students may think that a higher pH value means more acidic. Reinforce the opposite. • Reinforce that “concentrated” (having a high concentration of particles in mol/L) is different from “strong” (dissociates 100%), and “dilute” (having a low concentration of particles in mol/L) is different from “weak” (dissociates much less than 100%).
