Webb19 juni 2024 · sulfuric acid ( H 2 SO 4) barium hydroxide ( Br ( OH) 2) For a strong acid, [ H +] = [ A −] = concentration of acid if the concentration is much higher than 1 × 10 − 7 M. However, for a very dilute strong acid solution with concentration less than 1 × 10 − 7 M, the pH is dominated by the autoionization of water. (7.14.2) H 2 O ⇌ H ... Webb1 juni 2016 · Explanation: [H +] → pH = −log[H +] = pH. [OH −] → pH = − log[OH −] = pOH. pH → [H +] = 10−pH = [H +] pOH → [OH −] = 10−pOH = [OH −] 14 −pH = pOH. …

As we have seen, [H3O +] and [OH −] values can be markedly different from one aqueous solution to another. So chemists defined a new scale that succinctly indicates the concentrations of either of these two ions. pH is a logarithmic function of [H3O +]: pH = − log[H3O +]
