5 True/False Questions
colloid → The number of moles of solute dissolved per liter of solution.
solvation → The ratio of the number of moles of solute dissolved in one kilogram of solvent.
solubility → The maximum amount of solute that will dissolve in a given amount of solvent at a specific temperature and pressure.
saturated solution → Contains less dissolved solute for a given temperature and pressure than a saturated solution; has further capacity to hold more solute.
Tyndall effect → Describes a substance that cannot be dissolved in a given solvent.
