Web10 Apr 2024 · Explanation: Well, the pH of the seawater is 8.1, and so its pOH is: pOH = 14 − 8.1 = 5.9 The pOH of a substance is related through the equation, pOH = − log[OH −] [OH −] is the hydroxide ion concentration in terms of molarity. And so, we got: −log[OH −] = 5.9 [OH −] = 10−5.9 ≈ 1.26⋅ 10−6 M Answer link Webi) Q:Calculate the pH of a solution having a [H3O+] = 8.54 × 10-8 M. A:By definition, pH is given by: pH=−log10 [H3 O+] pH=−log10 (8.54⋅10−8) pH=7.07 ii) Q:What is the pOH of a solution having a pH of 8.50?
