Which of the following ions will contribute most to elevating the boiling point of H₂O?

Two beakers are placed in a sealed box at 25 °C. One beaker contains 30.0 mL of a 0.050 M aqueous solution of a nonvolatile nonelectrolyte. The other beaker contains 30.0 mL of a 0.035 M aqueous solution of NaCl. The water vapor from the two solutions reaches equilibrium. (a) In which beaker does the solution level rise, and in which one does it fall?

Explain how the addition of a solute affects the boiling point of a solvent.

Why does water boil at a higher temperature than butter, which is non-polar?

Arrange NaCl, Cl₂, CCl₄, and PCl₅ in order of increasing boiling point.
