etanolvíz

Etanolvíz, also known as ethanol-water mixture, is a solution composed of ethanol and water. The properties of such a mixture vary significantly depending on the proportions of ethanol and water. At room temperature, it is typically a clear, colorless liquid with a characteristic alcoholic odor. The miscibility of ethanol and water is complete, meaning they can be mixed in any ratio to form a homogeneous solution.

The creation of an ethanol-water mixture can be achieved through simple mixing of the two components. The process of mixing can generate heat, an exothermic reaction, particularly when high concentrations of ethanol are involved. This heat generation is a consequence of the intermolecular forces between ethanol and water molecules. The density of the mixture is generally lower than that of pure water but higher than that of pure ethanol, and it changes predictably with the concentration of ethanol.

Ethanol-water mixtures find widespread use across various industries and applications. In the pharmaceutical industry, they serve as solvents for many medicinal compounds and are used in the production of disinfectants and antiseptics. The food and beverage industry utilizes ethanol-water mixtures in the production of alcoholic beverages and as a solvent for flavorings and extracts. In laboratories, it is a common solvent for chemical reactions and analytical procedures. The flammability of ethanol-water mixtures is a key characteristic, and their flash point is dependent on the ethanol concentration. Safety precautions are therefore necessary when handling these solutions.
