Yes, a solution can exist in any of the three common phases of matter: solid, liquid, or gas. A solution is a homogeneous mixture where a solute is dissolved in a solvent, and this can occur regardless of whether the solvent and solute are solids, liquids, or gases. Here's a breakdown:Solid Solutions: Examples include alloys like brass (copper and zinc) or steel (iron and carbon). Liquid Solutions: The most common type, like saltwater (salt dissolved in water) or vinegar (acetic acid in water). Gaseous Solutions: Air is a classic example, a mixture of nitrogen, oxygen, and other gases.
