Concept introduction:
The colligative properties refer to those properties that are directly proportional to the number of particles. Thus these properties are only determined from the concentration and do not depend on the nature of the solute.
The depression in melting point, elevation in boiling point, and osmotic pressure are some of the colligative properties that depend on the number of particles of solute.

- Consider three test tubes. Tube A has pure water. Tube B has an aqueous 1.0 m solution of ethanol, C2H5OH. Tube C has an aqueous 1.0 m solution of NaCl. Which of the following statements are true? (Assume that for these solutions 1.0m=1.0M.) (a) The vapor pressure of the solvent over tube A is greater than the solvent pressure over tube B. (b) The freezing point of the solution in tube B is higher than the freezing point of the solution in tube A. (c) The freezing point of the solution in tube B is higher than the freezing point of the solution in tube C. (d) The boiling point of the solution in tube B is higher than the boiling point of the solution in tube C. (e) The osmotic pressure of the solution in tube B is greater than the osmotic pressure of the solution in tube C.arrow_forwardWill red blood cells swell, remain the same size, or shrink when placed in each of the solutions in Problem 8-101?
