An aqueous solution is a term used to describe a solution that is made up of water as the solvent. There are a variety of synonyms that can be used to describe different types of aqueous solutions. For example, a solution that is particularly acidic may be described as an acidic aqueous solution. Similarly, a solution that has a high concentration of salt may be referred to as a saline aqueous solution. Other synonyms for aqueous solutions include dilute solutions, concentrated solutions, and saturated solutions. Ultimately, the specific term used to describe an aqueous solution will depend on the composition and properties of the solution itself.
