Explanation:

In chemistry, aqueous is used to refer to a solution that contains water in it. This is primarily what differentiates a liquid and an aqueous solution. A liquid substance/solution has its particles moving freely (but not as free as gaseous particles). Examples are ethanol, methanol, water, oil, kerosene and hexane. However, an aqueous solution contains water (usually as a solvent). Example of this is an aqueous salt solution - where salt is dissolved in water. If the salt is dissolved in something else (for example absolute ethanol), this cannot be referred to as aqueous.
