5 Matching questions

  1. Brownian motion
  2. Henry's law
  3. boiling point elevation
  4. unsaturated solution
  5. solvation
  1. a The temperature difference between a solution's boiling point and a pure solvent's boiling point.
  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 jerky, random, rapid movements of colloid particles that results from collisions of particles of the dispersion medium with the dispersed medium.
  4. d 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. e 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 Multiple choice questions

  1. A quantitative measure of the amount of solute in a given amount of solvent or solution.
  2. Describes a substance that can be dissolved in a given solvent.
  3. A physical property of a solution that depends on the number, but not the identity, of the dissolved solute particles.
  4. The diffusion of solvent particles across a semipermeable membrane from an area of higher solvent concentration to an area of lower solvent concentration.
  5. The scattering of light by colloidal particles.
