Solutions obeying Raoult's law over the whole range are:
AIdeal ones
BNon-ideal
CAzeotropes
DSuspensions
Answer & Solution
Correct answer: A. Ideal ones
1. Raoult's law is the test applied across every concentration.
2. A solution obeying it throughout is an ideal solution.
3. One failing it anywhere is non-ideal.
