General Principles:
* "Like Dissolves Like": The principle of "like dissolves like" is crucial. Polar solvents like alcohol (ethanol) tend to dissolve polar solutes, while nonpolar solvents dissolve nonpolar solutes.
* Solubility is a Spectrum: Not everything dissolves perfectly. Some materials are highly soluble, while others only dissolve to a very small extent.
Soluble Solids in Alcohol:
* Sugars: Simple sugars like glucose, fructose, and sucrose are very soluble in alcohol.
* Salts: Some salts, like sodium chloride (table salt) and potassium chloride, are moderately soluble in alcohol. However, others are less soluble or practically insoluble.
* Aromatic Compounds: Many aromatic compounds (those with a benzene ring structure) are soluble in alcohol, including:
* Phenol
* Some dyes
* Certain organic acids (e.g., benzoic acid)
* Polymers: Certain polymers, like some resins and plastics, can be dissolved in alcohol to some extent.
Things That Are Less Soluble or Insoluble in Alcohol:
* Metals: Most metals are insoluble in alcohol.
* Many Inorganic Compounds: Salts with large, complex ions are often less soluble in alcohol.
* Lipids (Fats and Oils): Lipids are nonpolar and are generally not soluble in alcohol.
Important Considerations:
* Concentration: Even soluble materials have a limit to how much can dissolve in a given amount of alcohol. This is known as solubility.
* Temperature: Increasing temperature usually increases the solubility of solids in liquids.
* Type of Alcohol: Different types of alcohols (ethanol, methanol, isopropanol) have varying solubilities for different substances.
Safety Precautions:
* Always handle alcohols with care. They are flammable and can be toxic.
* Work in a well-ventilated area.
* Wear appropriate safety gear.
