Ethanol is alcohol, the most common monohydric alcohol.

Ethanol at room temperature and pressure is a flammable, volatile colorless transparent liquid, low toxicity, pure liquid is not directly drinkable; with a special flavor, and slightly stimulating; slightly sweet, and accompanied by stimulating spicy taste.

Flammable, its vapor can form explosive mixtures with air, can be mutually soluble with water in any ratio. It is miscible with chloroform, ether, methanol, acetone and most other organic solvents, relative density (d15.56) 0.816.

The deliquescence of ethanol

Because of the presence of hydrogen bonding, ethanol has strong deliquescence, and it can quickly absorb water from the air.

The polarity of the hydroxyl group also makes many ionic compounds soluble in ethanol, such as sodium hydroxide, potassium hydroxide, magnesium chloride, calcium chloride, ammonium chloride, ammonium bromide and sodium bromide, but sodium chloride and potassium chloride are slightly soluble in ethanol.

In addition, its non-polar hydrocarbon group makes ethanol soluble in some non-polar substances as well, such as most essential oils and many flavor enhancers, color enhancers, and pharmaceutical reagents.
