🤓 Based on our data, we think this question is relevant for Professor N/A's class at Ryerson University.
At 1/2 equivalence point: pH = pKa
pKa + pKb = 14
So we know that at 1/2 equivalence point:
pH = 14 – pKb
From the graph:
Consider the following curve for the titration of a weak base with a strong acid and answer each of the following questions.
At what volume of added acid does pH = 14 – pKb?
