WebOstwald’s dilution law. When acetic acid (a weak electrolyte) is dissolved in water, it dissociates partially into H+ or H3O+ and CH3COO– ions and the following equilibrium is obtained, CH3COOH + H2O ⇌ CH3COO– + H3O+. Applying law of chemical equilibrium, . In dilute solution, [H2O] is constant. WebFeb 9, 2024 · A common, but incorrect explanation of this law in terms of the Le Chatelier principle states that dilution increases the concentration of water in the equation HA + H 2 O → H 3 O + + A –, thereby causing this equilibrium to shift to the right.
