WebHCl H + + Cl - H 2 O H + + OH - We consider HCl to dissociate first, with H 2 O then responding. Since the concentration of acid is 2.0x10 -7 M, HCl will produce a [H +] of 2.0x10 -7. Using this as the initial [H +] in the equilibrium dissociation of water, we can find the equilibrium [H +] with an I.C.E. table: K w = [H +] eq * [OH -] eq WebHydrochloric acid is a strong acid and dissociates fully. HCl → H + + Cl - This means that the concentration of H + ions in 0.4 M HCl is higher than that in 0.4 M ethanoic acid, so its pH is lower and its acid reactions are faster. thin smoked pork chops recipe
