As a chemical expert with a deep understanding of solvent properties and their applications, I can provide a comprehensive analysis of why acetone is considered a better solvent than water in certain contexts.
Acetone, also known as propanone, is a widely used organic solvent with a unique set of properties that make it particularly effective for dissolving a broad range of substances. Here are several reasons why acetone is preferred over water in certain applications:
1. Polarity: Acetone is a polar solvent, but it is less polar than water. This intermediate polarity allows acetone to dissolve both polar and nonpolar substances, which water cannot do as effectively. The ability to dissolve a wider range of substances makes acetone a versatile solvent.
2. Evaporation Rate: Acetone has a lower boiling point and evaporates more quickly than water. This property is advantageous in applications where rapid drying is required, such as in nail polish removers and paint thinners.
3. Chemical Stability: Acetone is chemically stable and does not react with the substances it dissolves in many cases. This stability is crucial when the integrity of the dissolved material must be maintained.
4. Low Toxicity: Compared to some other solvents, acetone is relatively less toxic, making it safer to handle and use in various industrial and household applications.
5. Compatibility: Aceone is compatible with a wide range of materials, including plastics, rubber, and many types of paint and varnish. This compatibility makes it an excellent choice for cleaning and degreasing purposes.
6. Solubility: While water is a universal solvent, acetone can dissolve certain substances that water cannot, such as oils, fats, and some plastics. This unique solubility profile is beneficial in specific industrial processes.
7.
Use in Chromatography: As you mentioned, acetone is particularly useful in pigment chromatography due to its ability to resolve pigments on paper. Its slight polarity allows for the separation of pigments that might not be possible with water alone.
8.
Cleaning Applications: In cleaning applications, acetone's ability to dissolve grease and oil makes it an effective cleaning agent for various surfaces.
9.
Industrial Processes: In the manufacturing of certain products, such as adhesives, coatings, and plastics, acetone's solvent properties are critical for the dissolution and blending of raw materials.
10.
Environmental Considerations: Although acetone is not without environmental impact, it is generally considered to be more environmentally friendly than many other solvents due to its lower toxicity and higher biodegradability.
In conclusion, acetone's unique combination of properties—intermediate polarity, quick evaporation, chemical stability, low toxicity, compatibility with materials, and specific solubility characteristics—make it a superior solvent to water in various applications. Its effectiveness in pigment chromatography, along with its utility in cleaning, industrial processes, and environmental considerations, further solidifies its position as a preferred solvent in many scenarios.

Its slight polarity allows it to dissolve polar substances, and the fact that it is less polar than water allows greater resolution between pigments on paper. These reasons allow acetone to be a great solvent for pigment chromatography. Other solvents that are good are small alcohols for the same reason!
