2 examples of a liquid dissolved in a liquid
In general chemistry, a solution is a homogeneous mixture in which one substance (the solute) is dispersed at the molecular level in another substance (the solvent). When both components are liquids and form a single uniform phase, the mixture is a liquid–liquid solution and the liquids are often miscible.
Key identification rule. In a liquid–liquid solution, the solvent is the component present in the larger amount, and the solute is present in the smaller amount. If water is the solvent, the solution is called aqueous.
Step-by-step: choosing two valid liquid–liquid examples
- Select two liquids that mix to give one phase: the liquids should be miscible under ordinary conditions (no visible layering).
- Assign solvent and solute: decide which liquid is in greater amount (solvent) and which is in lesser amount (solute).
- State the solution type: if water is the solvent, classify as an aqueous solution; otherwise classify as a non-aqueous liquid solution.
Example answers
| Example (liquid in liquid) | Solute (smaller amount) | Solvent (larger amount) | Why it qualifies |
|---|---|---|---|
| Ethanol dissolved in water | Ethanol | Water | Ethanol and water are miscible and form a single homogeneous phase; water as solvent makes it an aqueous solution. |
| Acetic acid dissolved in water (vinegar-like solution) | Acetic acid | Water | Acetic acid and water are miscible; the mixture is uniform at the molecular level when water is the major component. |
Important nuance. “Solute” and “solvent” depend on amounts, not on chemical “strength.” For the same two liquids, reversing which one is in excess reverses solute/solvent labels.
Connecting to solution concentration (common in liquid–liquid mixtures)
Liquid–liquid solutions are often reported using percent by volume (also written as volume/volume percent). A standard definition is:
\[ \%\,\text{(v/v)} = \frac{V_{\text{solute}}}{V_{\text{solution}}}\times 100\% \]

Final answer
Two valid examples of a liquid dissolved in a liquid are ethanol dissolved in water and acetic acid dissolved in water; in each case the solute is the liquid present in the smaller amount and the solvent is the liquid present in the larger amount.
