A solution of acetone in ethanol — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

A solution of acetone in ethanol shows positive deviation from Raoult’s law because of the miscibility of these liquids with the difference of polarity. The acetone reduces the H-bonding strength between the ethanol molecules. Therefore, the mixture has a greater rate of evaporation and has a lower boiling point. It exhibits a positive deviation from Raoult’s law. SOLUTIONS 37 Therefore, the mixture has weaker intermolecular forces than the pure liquids.
