answered-by-expert Expert Answer

By acidic behaviour of an acid we mean that it dissociates to give Hydrogen ions.Now ions need some medium for mobilization and that medium is provided by water.In water the following equilibrium occurs between a weak acid (HA) and water, which acts as a base:

HA(aq) + H2O H3O+(aq) + A-(aq)
