WebThe constant Kw, sometimes called the ionic product of water remains unchanged at constant temperature (as all good constants should!). Kw = 1 x 10-14 mol 2 dm-6 (25ºC) From the stoichiometry of the equation, the concentration of hydrogen ions equals the concentration of hydroxide ions. Therefore the concentration of hydrogen ions in pure ... WebThe ionic product of water is the product of the molar concentration of [ H +] ions and [ OH -] ions. Dissociation of water can be expressed as H 2 O l Water ⇌ H + aq Hydrogen ion + OH - aq Hydroxide ion The equilibrium constant for this reaction is, K C = H + OH - H 2 O We know that, ionic products, K W = K C × H 2 O ∴ K W = H + OH -
