Acetic acid

Ethanoic acid (the systematic name for Acetic acid) is a 2 carbon molecule with carboxylic acid group -COOH. It has a Molecular weight of 60.05 and a pK_a value of 4.75.

Acetic acid reacts with alcohols in a condenstation reaction to form water and an ester with the functional group 'R'-COOC-'R'

It can be formed from the oxidation of Ethanol under acidic conditions and reflux using a strong oxidising agents such as potassium dichromate.

Ethanoic acid is a weak acid and only partially disasscociates in water to form an ethanoate ion CH₃COO^- and a hydrogen ion^[1]^[2]^[3].
