Question

Calculate the pH of a solution that has [OH] = 5.2 107 M. Answer                              A. pH = 5.20                 B. pH = 7.72                 C. pH = 6.28                 D. pH = 5.27                 E. pH = 7.00 Calculate the pH of a solution that has [OH] = 5.2 107 M. Calculate the pH of a solution that has [OH] = 5.2 107 M. pH = 5.20 pH = 7.72 pH = 6.28 pH = 5.27 pH = 7.00                 A. pH = 5.20                 B. pH = 7.72                 C. pH = 6.28                 D. pH = 5.27                 E. pH = 7.00

Explanation / Answer

pOH =-log(5.2*10^-7)

= 6.28

pH= 14-pOH =14-6.28 =7.72
