How does acid/base chemistry relate to solutions and solubility? Identify environmental factors, consequences and resolutions of water pollution. Learn about the qualitative and quantitative analysis of solutions including: the solubility table, ion dissociation and polarity. 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.

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. 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%).
