WebSince water can self-ionize, it creates an equilibrium between the ionized and non-ionized water. The equilibrium of water is described with the equation: K=[H3O+][OH−][H2O] Where K is the equilibrium constant equal to the concentration of products over the concentration of reactants. The ion concentrations of hydronium and hydroxide are equal to each other … Web26 jun. 2013 · Describes the self-ionization of water, defines acidic and basic solutions, and illustrates calculations using Kw.

Web5 jun. 2016 · To find the pOH, you have to take the -log of that concentration like this: -log ( 5 × 10−10 M) = 9.30. Thus, the pOH = 9.30. The second method is much easier. Just take the -log of the concentration of hydrogen ions: -log ( 2.0 ×10−5 M) = 4.70. That value represents the pH of the solution. To obtain the pOH from the pH just do 14 - pH = pOH.
