WebbHCl → 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. When alkalis are added, however, the ethanoic acid equilibrium position moves to the right, so eventually all the acid reacts, as shown in the equations below: NaOH ... For example, potassium oxide is about 83% potassium by weight, while potassium chloride is only 52%. Potassium chloride provides less potassium than an equal amount of potassium oxide.
