Explain why ethanoic acid is a weak acid.

Dear Student,..... The strength of acid is measured by the ability to lose a proton . An acid is called as strong if it completely ionizes in water while the weak acids do not ionize completely in water, rather they partially dissociates and form an equilibrium with both the acid and conjugate base in the solution. The ethanoic acid (acetic acid) is considered as a weak acid because it does not releases all of its hydrogen in water, rather it dissociates partially and establishes an equilibrium with its conjugate base. CH3COOH ---------> CH3COO- H+ ,. Regards.
