WebJun 19, 2024 · Calculate the pH of a solution with 1.2345 × 10 − 4 M HCl, a strong acid. Solution The solution of a strong acid is completely ionized. That is, this equation goes to completion HCl ( aq) H ( aq) + Cl − ( aq) Thus, [ H +] = 1.2345 × 10 − 4. pH = − log ( 1.2345 … WebOct 4, 2024 · Very pure distilled water that has had little contact with air will have a pH just below 7, usually 6.9. But this does not mean that distilled water is an acidic substance. Its acidity is only very slight, and this is further shown by the fact that normal rainwater actually has a pH of around 5.6 and is still safe to touch.
