Ethanoic Acid
is a
w
eak
acid with
high pH
and
low dissociation
Ethanoic
Acid is formed by:
Oxidation
of
ethanol
With
acidified potassium mangenate
(VII)
Carboxylic acids react with
alcohols
to give
esters
, in a condensation reaction, for example:
Ethanoic acid + ethanol ⇌ ethyl ethanoate + water (alcohol = -yl & carboxylic acid = -oate)
