http://acidsandbaseskate.weebly.com/ph-poh-h-and-oh.html WebpH Equation – Converting pH to H + In some situations, we know the pH and need to convert to the molar concentration of H + ions. For this, we need to invert the logarithm from the first equation, by raising 10 to the power of the negative pH. ... [OH –] Water and its pH. Pure water has a pH of 7 on the pH scale, meaning that it is neutral ... WebSo, now that we're adding the conjugate base to make sure we have roughly equal amounts, our pH is no longer 2. It might be somewhere like a 5. So now we have a strong buffer with a lot of capacity, but our pH of this buffer solution is very different from the pH of just the weak acid/conjugate base we started with.
