How are aqueous solutions of ethanol typically produced?

The production of aqueous solutions of ethanol typically involves the mixing of ethanol with water. This process results in a solution where ethanol is dissolved in water, creating an aqueous solution. Ethanol, being a polar molecule, mixes well with water, making the solution homogeneous.

Fermentation of sugar solutions using yeast primarily produces ethanol, but in this context, the focus is on the method of creating an aqueous solution. Although fermentation does lead to ethanol production, it does not directly result in an aqueous solution unless the produced ethanol is subsequently mixed with water.

Additionally, distillation of ethanol refers to separating ethanol from a mixture based on different boiling points, which does not directly create an aqueous solution of ethanol.

Filtration involves separating solid particles from fluids and is not a method used for creating solutions of ethanol in water.

Therefore, mixing ethanol with water is the correct and straightforward method for producing aqueous solutions of ethanol.
