Boiling point of a non-homogeneous mixture of immiscible liquids is _____________ that of any one of its separate components?
Correct answer: B. Lower than
- A. Higher than
- B. Lower than
- C. Equal to
- D. Either A. or B.; depends on the liquids
Explanation
Immiscible liquids boil when the sum of their vapour pressures reaches atmospheric pressure. Since each liquid contributes vapour pressure, this condition is reached below the boiling point of either pure component.
