Explanation:
Hello,
In this case, for the acid dissociation of formic acid (HCOOH) we have:
Whose equilibrium expression is:
That in terms of the reaction extent is:
Thus, solving for which is also equal to the concentration of hydrogen ions we obtain:
Then, as the pH is computed as:
The pH turns out:
