It depends on what you mean by "alcohol." If you are referring to alcoholic beverages, then the solute is ethanol (ethyl alcohol) and the solvent is water.

However, if you are referring to alcohol as a chemical compound, then the answer depends on what the alcohol is dissolved in.

Here are some examples:

* Ethanol in water: Ethanol is the solute, and water is the solvent.

* Ethanol in gasoline: Ethanol is the solute, and gasoline is the solvent.

* Methanol in water: Methanol is the solute, and water is the solvent.

* Isopropanol in water: Isopropanol is the solute, and water is the solvent.

In general, when discussing alcohol as a solute, it's important to specify the type of alcohol and the solvent it's dissolved in.
