Big Ideas
Properties of solutions
can be described
qualitatively and
quantitatively, and can
be predicted
People have a
responsibility to
protect the
integrity of Earth’s
atmosphere
Living things
depend for their
survival on the
unique physical
and chemical
properties of
water
Guiding Questions
Describe the
unique
characteristics of
water as a solvent.
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.

Activity: Trivia Board Games
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.
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%).
