Since [H+]·[OH-] = 10-14 at 25C, if [H+] is known, the [OH-] can be calculated and vice versa. pH = -log [H+] So if [H+] = 10-6 M, pH = 6 pOH = -log [OH-] So if [OH-] = 10-8, pOH = 8 Together, pH + pOH = 14. Complete the following chart: [H+] pH [] pOH Acidic or Basic 1. 10-5 M 5 10-9 M 9 Acidic 2. 7 3. 10-4 M 4. 10-2 M 5. 11 6. 12 7. 10-5 M 8. 10-11 M 9. 13 10. 6 pH and pOH CONTINUED Calculate the pH of the solutions below. 0.01 M HCl 0.0010 M NaOH 0.050 M NaOH 0.030 M HBr 0.150 M KOH
