  1. a The maximum amount of solute that will dissolve in a given amount of solvent at a specific temperature and pressure.
  2. b Contains less dissolved solute for a given temperature and pressure than a saturated solution; has further capacity to hold more solute.
  3. c The additional pressure needed to reverse osmosis.
  4. d A type of heterogeneous mixture whose particles settle out over time and can be separated from the mixture by filtration.
  5. e The ratio of the number of moles of solute dissolved in one kilogram of solvent.

5 Multiple choice questions

  1. Describes two liquids that are soluble in each other.
  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. Contains more dissolved solute than a saturated solution at the same temperature.
  4. 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.
  5. Describes a substance that can be dissolved in a given solvent.

5 True/False questions

  1. Brownian motionThe jerky, random, rapid movements of colloid particles that results from collisions of particles of the dispersion medium with the dispersed medium.

          

  2. vapor pressure loweringThe lowering of vapor pressure of a solvent by the addition of a nonvolatile solute to the solvent.

          

  3. freezing point depressionThe temperature difference between a solution's boiling point and a pure solvent's boiling point.

          

  4. Tyndall effectThe scattering of light by colloidal particles.

          

  5. 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.
