General Chemistry II Lab Final Exam
Questions and Answers (Latest 2026)
A pure solvent has a higher freezing/melting point than the
same solvent in a solution - Correct Answers ✅True
The actual freezing/melting point of a solvent in solution can
be affected by ion pairing (assuming the solute is ionic) -
Correct Answers ✅True
Generally speaking, the freezing/melting point of a solvent
will increase as solute is added. - Correct Answers ✅False
Generally speaking, adding more solute to a pure solvent
affects the freezing/melting point of the solvent less than
does adding a smaller amount of solute - Correct Answers
✅False
A well-constructed graph will have axis increments that are
uniform. - Correct Answers ✅True
The origin graph is always assumed to be (0, 0) - Correct
Answers ✅False
Molality is defined as - Correct Answers ✅Mole solute / kg
solvent
As a substance heats (or cools), it's temperature changes. -
Correct Answers ✅True

Questions and Answers (Latest 2026)
As a pure substance changes phase (for example, goes from
a gas to a liquid or goes from a solid to a gas), its
temperature changes. - Correct Answers ✅False
At the temperature at which a phase change occurs, two
phases are in equilibrium. (For example, at temperature at
which evaporation occurs, the liquid and the gas are in
equilibrium.) - Correct Answers ✅True
The liquid state of a solution freezes at constant temperature.
- Correct Answers ✅False
The freezing point of a liquid solution is higher than the
freezing point of a pure liquid. - Correct Answers ✅False
Supercooling is not a colligative property - Correct Answers
✅True
Molality is _. - Correct Answers ✅Mol solute / kg solvent
A chemical formula gives the following information: - Correct
Answers ✅1. The elemental composition of a substance
2. The ratio in which elements combine to form the substance
3. The number of ions into which the substance dissociates
