WebMar 28, 2024 · What is the pH of these solutions? pOH = 5.55 [ H 3 O +] = 10 –11 M [ O H −] = 10 –8 M Solution From Equation 15.8. 3, pH + pOH = 14.00. Therefore, pH = 14.00 – pOH = 14.00 – 5.55 = 8.45. From Equation 15.8. 1, p H = − log [ H 3 O +] = − log ( 10 − 11) = − ( − 11) = 11 From Equation 15.8. 2, p O H = − log [ O H −] = − log ( 10 − 8) = − ( − 8) = 8 .
