Which term refers to volatile chemicals dissolved in alcohol solutions?

• A. Tinctures
• B. Liquid medications
• C. Solutions
• D. Spirits

Answer: (D)

Spirits refer to volatile aromatic substances dissolved in an alcohol solvent. When a compound is highly volatile, its defining feature is its tendency to evaporate and carry a strong aroma. Dissolving that volatile essence in alcohol creates a concentrated liquid where the aroma and volatility are preserved, so the preparation is described as a spirit.

Tinctures are alcoholic extracts of plant materials and can include a mix of volatile and nonvolatile constituents, not specifically defined by volatility alone. A generic solution or liquid medication lacks the emphasis on a volatile aromatic component, so they don’t capture the defining idea. Hence, a volatile chemical dissolved in alcohol is best described as a spirit.
