5 Matching questions

  1. solvation
  2. colloid
  3. vapor pressure lowering
  4. immiscible
  5. supersaturated solution
  1. a Describes two liquids that can be mixed together but separate shortly after you cease mixing them.
  2. b The lowering of vapor pressure of a solvent by the addition of a nonvolatile solute to the solvent.
  3. c 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.
  4. d Contains more dissolved solute than a saturated solution at the same temperature.
  5. e Hetergeneous 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.

5 Multiple choice questions

  1. A physical property of a solution that depends on the number, but not the identity, of the dissolved solute particles.
  2. The ratio of the number of moles of solute dissolved in one kilogram of solvent.
  3. The jerky, random, rapid movements of colloid particles that results from collisions of particles of the dispersion medium with the dispersed medium.
  4. Contains less dissolved solute for a given temperature and pressure than a saturated solution; has further capacity to hold more solute.
  5. The overall energy change that occurs during the solution formation process.

5 True/False questions

  1. solubleDescribes a substance that cannot be dissolved in a given solvent.

          

  2. miscibleDescribes two liquids that can be mixed together but separate shortly after you cease mixing them.

          

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

          

  4. suspensionThe 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. Henry's lawStates 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.
