The naming of acetic acid

Acetic acid is both common names, but also the International Union of Pure and Applied Chemistry provides the official name. Commonly known as acetic acid, the name comes from the Latin word representation vinegar "acetum". Of anhydrous acetic acid at slightly below room temperature (16.7 ℃), can be converted into a corrosive ice crystals, and at lower temperatures can be volatile, so often called anhydrous acetic acid as acetic acid, ice acetic acid, ice form acetic acid, acetic acid ice.

The empirical formula of glacial acetic acid (ie, the simplest formula) for the CH ₂ O, chemical formula (ie formula) for the C ₂ H4O ₂. Often written as CH ₃-COOH, CH ₃ COOH or CH ₃ CO ₂ H to highlight one of the carboxyl groups, indicating that more accurate structures. Loss of H ions formed after acid anion. The most common acetate AcOH or official abbreviations HOAc, wherein Ac represents the acetyl group of acetic acid (CH ₃ CO). Acid-base neutralization reaction can also be expressed HAc acetic acid, wherein Ac represents the acid anions (CH ₃ COO), but many people think that this is likely to cause misunderstanding. In both cases, Ac chemical elements should not be the abbreviation actinide confusion.
