  1. a 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.
  2. b 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.
  3. c Contains the maximum number of dissolved solute for a given amount of solvent at a specific temperature and pressure.
  4. d Describes two liquids that are soluble in each other.
  5. e The ratio of the number of moles of solute in solution to the total number of moles of solute and solvent.

5 Multiple choice questions

5 True/False questions

  1. heat of solutionThe overall energy change that occurs during the solution formation process.

          

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

          

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