What type of deviation from Raoult's law is shown by mixture of ethanol and acetone ? Give reason. What will happen to the boiling point of the solution on mixing ethanol and acetone ?
Marking-scheme solution
• Positive Deviation
• Due to stronger interaction of ethanol-ethanol than ethanol-acetone
• Boiling point will decrease
