Butanoic  acid  dissociate  in  water  as  below

C3H7COOH  (aq)    ↔  C3H7COO^-(aq)   +  H^+(aq)


Butanoic acid   dissociate in water  to  produce  BUtanoate  ion (C3H7COO^-) and  Hydrogen ions   (H^+).  Butanoic acid  is a  week acid  thus it dissociate  partially  in  water.  The production of   hydrogen  ion is because   Butanoic  acid is an acid.

Answer:


                 C₃H₇COOH (aq) + H₂O (l)     ↔    C₃H₇COO⁻ (aq) + H₃O⁺ (aq)


Explanation:

                      Among Organic compounds carboxylic acids are acidic in nature. This acidity of carboxylic acids can be explained by the stability of conjugate base called as Carboxylate ion (a general name). This stability of Carboxylate ions originate due to resonance between the oxygen containing negative charge and carbonyl group.


Therefore, when carboxylic acids are dissolved in water, the water molecules act as base and abstracts proton from carboxylic acid and forms a conjugate acid i.e. H₃O⁺. And the coarboxylic acid is converted into its corresponding conjugate base (carboxylate Ion)
