Arrange the boiling points of the aqueous solutions, relative to pure water: Assume complete dissociation for the ionic compounds. Highest boiling point 0.38 m CzHs OH 0.32 m NH; 0.19 Naz SO4 0.11 m NaCl HzO Lowest boiling point

Respuesta :

The boiling points of aqueous solutions based on pure water are as follows, in descending order of boiling points:

  1. 0.38mCzHsOH - Highest boiling point
  2. 0.32mNH4
  3. 0.19m Na2SO4
  4. 0.11m NaCl
  5. H2O (pure water) -Lowest boiling point

The boiling point of a solution increases as the concentration of the solute (dissolved substance) increases. The presence of ions and other dissolved particles in solution increases the vapor pressure of the solvent (water in this case), requiring more energy to reach its boiling point.

Ionic compounds such as NaCl and Na2SO4 completely dissociate into ions when dissolved in water, and thus have a greater impact on boiling points than non-ionic compounds such as CzHsOH.
