WebThe pOH value can be calculated using pH or hydrogen ion concentration ( [ H +]). Both hydrogen ion and hydroxide ion are co-related by the following equation: [ O H −] = K w [ H +] Here, Kw is the water ionization constant. Now we apply logarithm to both sides and get: pOH = pKw – pH We get an approximation of the value of pOH. pOH = 14 – pH WebDersom man kjenner pH-verdien kan man finne [H3O+] ved å bruke formelen [H3O+]=10-pH (formel 2). Det finnes også en tilsvarende måleenhet til pH, kalt pOH, som måler konsentrasjonen av OH- ioner.
