current: sodium chloride (NaCl), hydrochloric acid (HCl) and sugar

(C6H12O6).
ff

Sodium chloride (NaCl) is an ionic compound and conducts since it

forms ions in solution. Hydrochloric acid (HCl) is a polar compound and
ff ff ff ff ff ff ff ff ff ff ff ff

conducts since it forms ions in solution. Sugar (C6H12O6) is a molecular

compound but does not form ions in solution so it does not conduct.

Explain how and why the presence of a solute affects the boiling point of a

solvent.
ff

The presence of a solute raises the boiling point of a solvent by

lowering the vapor pressure of the solvent. With this lower vapor

pressure, more heat (a higher boiling point) is required to raise the
