in water, HC2H3O2 does not ionize since it is a weak acid CsOH, however, dissociates. Molecular: HC2H3O2(aq) + CsOH(aq) --> CsC2H3O2(aq) + H2O(l) Ionic: HC2H3O2(aq) + Cs+(aq) + OH-(aq) --> Cs+(aq) + C2H3O2-(aq) + H2O(l) Net Ionic: HC2H3O2(aq) + OH-(aq) --> C2H3O2-(aq) + H2O(l) Molecular fomula is where all compound are written as you would see them in reagent bottles. Ionic equation is where all compounds that dissociate in water are written as ions if in aqueous environment Net ionic equation is same as ionic equation, but species identical on both sides of equation (spectator ions) are not written. Hope it helps :D Solution in water, HC2H3O2 does not ionize since it is a weak acid CsOH, however, dissociates.
