A solution failing Raoult's law over the full range is:
AIdeal one
BAzeotrope
CSaturated
DNon-ideal
Answer & Solution
Correct answer: D. Non-ideal
1. An ideal solution obeys the law at every concentration.
2. Any departure from it makes the solution non-ideal.
3. Its vapour pressure is then higher or lower than predicted.
