Chem 120 Exam 4 Study Questions with
Detailed Answers 2025
solution -Correct Answer ✔a homogeneous mixture of two or more substances
with each substance retaining its own chemical identity
solvent -Correct Answer ✔the component of a solution that is present in the
greatest amount
solute -Correct Answer ✔a component of a solution that is present in the lesser
amount compared to the solvent
solubility -Correct Answer ✔the maximum amount of solute that will dissolve in a
given amount of solvent under a given set of conditions
Henry's Law -Correct Answer ✔the amount of gas that will dissolve in a liquid at a
given temperature is directly proportional to the partial pressure of the gas above
the liquid
Saturated solutions -Correct Answer ✔a solution that contains the maximum
amount of a solute that can be dissolved under the conditions as which the solution
exists
supersaturated solutions -Correct Answer ✔an unstable solution that temporarily
contains more dissolved solute than present in a saturated solution

unsaturated solution -Correct Answer ✔a solution that contains less than the
maximum amount of solute that can be dissolved under the conditions at which the
solution exists
concentrated solution -Correct Answer ✔a solution that contains a large amount of
solute relative to the amount that could dissolve
dilute solution -Correct Answer ✔a solution that contains a small amount of solute
relative to the amount that could dissolve
Aqueous solution -Correct Answer ✔a solution in which water is the solvent
non aqueous solution -Correct Answer ✔a solution in which a substance other than
water is the solvent
Factors that affect rate of solution formation -Correct Answer ✔1) state of the
subdivision of the solute (crushed vs whole)
2) the degree of agitation during solution preparation
3) the temperature of the solution components
concentration -Correct Answer ✔the amount of solute present in a specified
amount of solution
percent by mass -Correct Answer ✔the mass of solute in a solution divided by the
total mass of solution multiplied by 100
