WebbThe pH of a solution is 8.22. What are pOH, [H + ], and [OH − ]? Solution Because the sum of pH and pOH equals 14, we have 8.22 + pOH = 14 Subtracting 8.22 from 14, we get pOH = 5.78 Now we evaluate the following two expressions: [H+] = 10−8.22 [OH−] = 10−5.78 So [H+] = 6.0 × 10−9 M [OH−] = 1.7 × 10−6 M Test Yourself The pOH of a solution is 12.04.
