Webb11 maj 2016 · Explanation: You can simply find the pH from the concentration of H + which is equal to: [H +] = [H Cl]0. Then, pH = − log[H +] From the water dissociation constant kw = [H +][OH −] = 1.0 × 10−14 we can take the −log of both parties, we get: −logkw = −log[H +] −log[OH −] = 14. knowing that pH = − log[H +] and pOH = − log[OH ... WebbCalculate the pH of 10 -8 M HCl. If we use the relation, pH = – log [H 3 O + ], we get pH equal to 8. But this is not correct because an acidic solution cannot have pH greater than …
Webb3 apr. 2024 · Complete answer: As we know that HCl is a strong acid, so its pH will be less than 7. The concentration of HCl = 10 − 8 M. Total [ H +] = [ H +] obtained from HCL + [ H … WebbThus, the 10^-8 M HCl solution has a pH of 8. Here, a very low concentration of acid is present, that is why the pH is above neutral. With high concentration of acids, pH is generally less than 7 ...
