For two liquids A and B to form an ideal solution
Detailed Explanation:
An ideal solution follows Raoult's law where intermolecular forces between A–A, B–B, and A–B molecules are approximately equal.
Enthalpy of mixing (ΔHmix) = 0 because no heat is absorbed or released during mixing.
Entropy of mixing (ΔSmix) > 0 (positive) due to increased randomness, and Free energy of mixing (ΔGmix) < 0 (negative), making the process spontaneous.
