Question

Which of the following components form an ideal solution?

• A. Benzene and toluene
• B. Acetone and aniline
• C. Ethyl alcohol and benzene
• D. Water and nitric acid

Answer 1

The correct option is A Benzene and toluene

The solutions which obey Raoult's law over the entire range of concentration are known as ideal solutions.

For ideal solution, the enthalpy of mixing of the pure components to form the solution is zero and the volume of mixing is also zero, i.e.,

${△}_{mix}H=0$ and ${△}_{mix}V=0$

Thus type of solution is a solution of benzene and toluene.
