Calculate the pH values of the following solutions. All solutions are prepared in water at 25 ºC unless noted otherwise. Kw = 1.0 × 10−14 = [H3O+ ][OH− ] at 25 ºC The neutral pH of pure water is 7.00 at 25 °C. If the Kw is 1.47×10−14 at 40 °C, calculate the neutral pH of pure water at 40 °C. A neutral pH means the pH of a solution when [H3O+ ] = [OH− ]
