Take a look at the equation describing the dissociation of water at 25 C: [HO] [OH] = 10 When calculating the pH of a base-derived solution, we're, in fact, counting the number of OH particles! In reality, we're computing the pOH of the solution. To convert our result to the desired pH scale, we need to use the following equation: (Psst!

Wunderkerzen gibt es unter anderem bei diesen Hndlern. Calculate the pH when two weak acids are present in a solution. If the pH is between 6 and 8, the contribution due to autoionization of water to \(\ce{[H+]}\) should also be considered. Secondly, pH calculations are a very good introduction to the concept of chemical equilibrium in the solution. 5. The next method uses the formula derived earlier.
