What is Acetic Acid?
Acetic Acid is a monocarboxylic acid with a chemical formula C2H4O2. It is also known as Methanecarboxylic acid or Ethanoic acid. This organic compound consists of a carboxyl group attached to a methyl group and is a colorless liquid with a pungent smell. The carboxylic acid group is the functional group of acetic acid. It partially dissociates in water, therefore, it is said to be a weak acid. Acetic acid was synthesized for the first time by German chemist Hermann Kolbe in the year 1845. Another name for water-free acetic acid is glacial acetic acid. The PH of 1 mM of acetic acid is about 3.91.
