SOLUTIONS AND COLLIGITIVE PROPERTIES KEY
CONCEPTS AND APPLICATIONS IN CHEMISTRY
What is seawater classified as? - answer-A solution,
specifically a homogeneous mixture of salts and What
occurs when solute-to-solvent attractions are weaker than
solute-to-solute and solvent-to-solvent attractions? -
answer-The solution will only form if the energy difference
is small enough to be overcome by the increase in entropy
from mixing.
What is the relationship between intermolecular forces and
solution formation? - answer-Energy changes in solution
formation involve differences in attractive forces between
solute and solvent particles.
water.
What happens when you drink seawater? - answer-It can
cause dehydration and diarrhea due to the higher salt
concentration than in your cells.
What is the majority component of a solution called? -
answer-The solvent.
,What is the minority component of a solution called? -
answer-The solute.
What drives the spontaneous mixing of solutions? -
answer-Nature's tendency toward spontaneous mixing and
the increase in entropy.
What is entropy in the context of solutions? - answer-A
measure of energy dispersal in a system, driving the
mixing of substances.
What is solubility? - answer-The maximum amount of
solute that can be dissolved in a given amount of solvent.
What does the phrase 'like dissolves like' refer to? -
answer-A chemical will dissolve in a solvent if it has a
similar structure to the solvent.
What are miscible liquids? - answer-Two liquids that are
mutually soluble in each other, such as alcohol and water.
What are immiscible liquids? - answer-Liquids that do not
mix, such as oil and water.
, What is the effect of temperature and pressure on
solubility? - answer-The solubility of one substance in
another can vary with changes in temperature and
pressure.
What is the role of energy in the solution process? -
answer-Energy is required to overcome solute-solute and
solvent-solvent attractive forces, while new solute-solvent
attractions release energy.
What is a common characteristic of gases in terms of
solubility? - answer-Gases are always soluble in each
other.
What happens to the solubility of alcohols as they become
less polar? - answer-They become less soluble in water
and more soluble in nonpolar solvents like hexane.
What is the significance of the cell wall in relation to
seawater? - answer-The cell wall acts as a barrier to
solute movement, causing water to flow out of cells when
seawater is ingested.
