Acetic acid is a common name for acetic acid. Because the freezing point of acetic acid is relatively high, it can solidify at room temperature, like ice, so it is called glacial acetic acid.

Glacial acetic acid, also known as anhydrous acetic acid, has a certain corrosive effect on human body and should be diluted when used. Generally speaking, glacial acetic acid can only be eaten if its content cannot exceed 3 -4%, but it has no nutritional value. Acetic acid, also known as acetic acid, is an organic compound and a typical fatty acid. It is recognized as the source of sour taste and pungent smell in vinegar. Acetic acid is a simple carboxylic acid and an important chemical reagent. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic liquid.
