Calculate [H 3 O +], [OH −], pH, and pOH for pure water at 40 °C. The ionization constant for water (K w) is $9.311×10^{−14}$ at 60 °C. WebIn a similar way, if I know the pOH is 11, then the pH is 3 and this is an acidic solution. For the examples below, convert each hydroxide ion concentration into a pOH. Identify each as an acidic pOH or a basic pOH. Example #3: 0.0045 M pOH = −log 0.0045 pOH = −(−2.35)
