What is the approximate of the weak acid?

pH = 7 for titration of the strong acid; pH = 10 for titration of the weak acid. pH = 2 for titration of the strong acid; pH = 6 for titration of the weak acid. pH = 5 for titration of the strong acid; pH = 8 for titration of the weak acid. pH = 9 for titration of the strong acid; pH = 12 for titration of the weak acid. pH at the equivalence point for each of the acids?

Explanation / Answer

A)

The equivalence of the Strong acid + Strong base is always the half of the line... as I see from the diagram I would say it is about 7... For that of the Strong base + weak acid... which is the purple line, I see the half point about 10

Choose the first option (pH 7 and then 10)

C)

The pKa = pH when it is exatly half of the buffer area

The buffer area here is from the next volumes:

from 0 to 40 ml... half is about 20 ml... intersect now with the GREEN line

then go to the pH... I see it about 2

pKA must be about 2

Nearest answer is 2.5

so pKa = 2.5
