Substance that dissolves another substance or substances to form a solution.

Substance that dissolves another substance or substances to form a solution.

• A. Solvents
• B. Surfactants
• C. Coatings
• D. Degreasers

Answer: (A)

A solution forms when a solvent dissolves a solute, making the solvent the substance that does the dissolving. The solvent is typically the component in the greater amount that carries the dissolved material, as in water dissolving salt to make a saline solution. Among the options, the term that fits this role is the solvent. Surfactants modify how substances interact at interfaces and can help mix or solubilize certain compounds, but they aren’t defined as the primary dissolving medium for forming a solution. Coatings are films applied to surfaces, and degreasers are cleaners designed to remove grease; their primary functions aren’t about acting as the dissolving medium in a solution.
