How are ph and poh scales related
WebpH and pOH. Adding an acid to water increases the H 3 O + ion concentration and decreases the OH-ion concentration. Adding a base does the opposite. Regardless of what is added to water, however, the product of the concentrations of these ions at equilibrium is always 1.0 x 10-14 at 25 o C. [H 3 O +][OH-] = 1.0 x 10-14. The table below lists pairs of … Web22 de nov. de 2010 · pH and pOH are a measure of the concentration of the hydronium ions and hydroxyl ions respectively in the solution. pH = -log [H+] pOH = -log [OH-] and they are related: pH + pOH = 14.
