  2. b The diffusion of solvent particles across a semipermeable membrane from an area of higher solvent concentration to an area of lower solvent concentration.
  3. c The lowering of vapor pressure of a solvent by the addition of a nonvolatile solute to the solvent.
  4. d The number of moles of solute dissolved per liter of solution.
  5. e The maximum amount of solute that will dissolve in a given amount of solvent at a specific temperature and pressure.

5 Multiple choice questions

  1. 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.
  2. Contains the maximum number of dissolved solute for a given amount of solvent at a specific temperature and pressure.
  3. The ratio of the number of moles of solute in solution to the total number of moles of solute and solvent.
  4. Describes two liquids that can be mixed together but separate shortly after you cease mixing them.
  5. Describes a substance that can be dissolved in a given solvent.

5 True/False questions

  1. miscibleDescribes two liquids that are soluble in each other.

          

  2. unsaturated solutionContains less dissolved solute for a given temperature and pressure than a saturated solution; has further capacity to hold more solute.

          

  3. colloidHetergeneous mixtures containing particles larger than solution particles but smaller than suspension particles that are categorized according to the phases of their dispersed particles and dispersing mediums.

          

  4. colligative propertyThe number of moles of solute dissolved per liter of solution.

          

  5. freezing point depressionThe difference in temperature between a solution's freezing point and the freezing point of its pure solvent.
