5 Matching questions

  1. unsaturated solution
  2. mole fraction
  3. boiling point elevation
  4. solvation
  5. molarity
  1. a The process of surrounding solute particles with solvent particles to form a solutions; occurs only where and when the solute and solvent particles come in contact with each other.
  2. b The ratio of the number of moles of solute in solution to the total number of moles of solute and solvent.
  3. c The number of moles of solute dissolved per liter of solution.
  4. d Contains less dissolved solute for a given temperature and pressure than a saturated solution; has further capacity to hold more solute.
  5. e The temperature difference between a solution's boiling point and a pure solvent's boiling point.

5 Multiple choice questions

  1. The difference in temperature between a solution's freezing point and the freezing point of its pure solvent.
  2. The diffusion of solvent particles across a semipermeable membrane from an area of higher solvent concentration to an area of lower solvent concentration.
  3. The overall energy change that occurs during the solution formation process.
  4. States that at a given temperature, the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid.
  5. Describes a substance that can be dissolved in a given solvent.
