Question

Ideal solution is formed when its components :

• A. have zero heat of mixing
• B. have zero volume change
• C. obey Raoult's law
• D. can be converted into gases

Answer 1

Answer: (A), (B), (C)

The correct options are
A obey Raoult's law
B have zero heat of mixing
C have zero volume change

An Ideal solution is the one which obeys Roault's Law at all concentrations and emperature and during the formation of which no change in enthalpy and volume takes place i.e.,
$P_A=P{o}_A{X}_A$.
$P_B=P{o}_B{X}_B$.
If the solution is made up of two components which are liquids then,
$\Delta H_{[}mixing]=o$.
$\Delta V_{[}mixing]=o$.
In the ideal solutions, solvent- solute interactions are equal to solute-solute and solvent-solvent interactions.
Hence option A,B&C are correct.
