According to Arrhenius theory, acids are substances that dissociate in water to give X ions and bases are substances that produce Y ions. X and Y respectively are

According to Arrhenius theory, acids are substances that dissociate in water to give hydrogen ions ${\mathrm{H}}^{+}\left(\mathrm{aq}\right)$ and bases are substances that produce hydroxyl ions ${\mathrm{OH}}_{\left(\mathrm{aq}\right)}^{-}$.
