Worksheet: Ideal Solutions

Q1:

Which of the following is not a typical property of a solution?

  • ASolutions share the physical state of the solvent, not the solutes.
  • BSolutions consist of solutes dissolved in a solvent.
  • CThe components of the solute within a solution are dispersed on the molecular level.
  • DSolutions are unstable over long periods, and solutes will evaporate or precipitate out spontaneously.
  • EThe concentration of a solute can be varied continuously, up to the limit of solubility.

Q2:

When K N O 3 dissolves in water, the temperature of the water decreases. Is the resulting solution an ideal solution?

  • AThe dissolution is exothermic, and the resulting solution is ideal: dissolution of the solute is complete and ions are completely dissociated.
  • BThe dissolution is endothermic, and the resulting solution is ideal: dissolution of the solute is complete and ions are completely dissociated.
  • CThe dissolution is endothermic, and the resulting solution is not ideal: the solute will precipitate over time in order to release heat energy from the system.
  • DThe dissolution is endothermic, and the resulting solution is not ideal: the enthalpy of mixing for an ideal solution must be zero.
  • EThe dissolution is exothermic, and the resulting solution is not ideal: the enthalpy of mixing for an ideal solution must be zero.
