Question

Write two differences between ideal and non-ideal solutions.

Hint:

Ideal → Similar intermolecular forces. Non-ideal → Different intermolecular forces.

Answer 1

Ideal Solution:

• Obeys Raoult’s law at all concentrations.
• No enthalpy change on mixing (\(\Delta H_{mix} = 0\)).
• No volume change on mixing.

Non-Ideal Solution:

• Deviates from Raoult’s law.
• Shows heat change on mixing.
• Volume change occurs.
