A solution of acetone in ethanol is a homogeneous mixture where acetone (C₃H₆O) is the solute, and ethanol (C₂H₅OH) is the solvent. Both acetone and ethanol are polar organic compounds and mix well due to their mutual miscibility.

Key Features of the Solution:

1. Polarity: Both are polar solvents, with acetone slightly less polar than ethanol. This polarity allows them to mix at all proportions.
2. Hydrogen Bonding: Ethanol can form hydrogen bonds with acetone, stabilizing the solution.
3. Applications:
   • Laboratory Use: As a cleaning agent or solvent for chemical reactions.
   • Industrial Use: In coatings, inks, or as an intermediate for other chemical formulations.

Composition and Concentration:

The ratio of acetone to ethanol can vary depending on the intended use. For example:

• 50:50 (volume ratio) might be used as a general-purpose solvent.
• Specific ratios are tailored for scientific or industrial requirements.

Safety Note: This solution is flammable and should be handled in well-ventilated areas, away from ignition sources.
