How do weak bases dissociate in water
WebA weak base is a base that, upon dissolution in water, does not dissociate completely, so that the resulting aqueous solution contains only a small proportion of hydroxide ions and the concerned basic radical, and a large proportion of undissociated molecules of the base. pH, Kb, and Kw [ edit] WebNeutralized by a base Acid donates a proton Acid Produces OH- in water Base has a slippery feel Base identify the acid & base: CO32− (aq)+H2O (l)⇋HCO3− (aq)+OH− (aq) acid (proton donor) H2O, base (proton acceptor) CO32− H2CO3 (aq)+H2O (l)⇋H3O+ (aq)+HCO3− (aq) acid (proton donor) H2CO3, base (proton acceptor) H2O examples of strong acids HClO4 …
