Calculate oh- from h+
WebJun 4, 2013 · This video is a quick tutorial on how to solve for pOH, [H+],[OH-] when given the pH. If you are given the pH of the solution, finding the [H+] and [OH-] is ... WebMethod 1. To find the hydroxide ion concentration, [OH-], you need the pOH rather than the pH. Fortunately, the pH and pOH are connected by a simple relationship. For aqueous solutions at 25ºC, pH + pOH = 14. So given a pH of, say 4, the pOH is 10. If the pH is 11, the pOH is 3. Once you know the pOH, you can find the [OH-] using the following ...

WebMar 28, 2024 · p O H = − log [ 10 − 7] = − ( − 7) = 7. Thus, both the pH = 7 and pOH = 7 for pure water. This makes sense, since the pH and pOH should sum to 14, as shown in Equation 15.8. 3 above. As previously noted, temperature matters. However, if the temperature is not cited, a temperature of 25°C (room temperature) may be assumed. Webarrow_forward.
