Question
consider the titration of a weak acid with a dtrong base. at what point of titration will pH equal pKa and why?
a) pH will never equal pKa
b) when the amount of acid and its conjugate base are equal(which is the point at which the volume of titrant is 1/2V(e) or half way to the equivalence point).
c) at the equivalence point when all of the weak acid is consumed.
d) at some point after passing the equivalence point when there is sufficient amount of strong base to make the pH high enough that it can equal the pKa of the weak acid.
e)
Explanation / Answer
d) at some point after passing the equivalence point when there is sufficient amount of strong base to make the pH high enough that it can equal the pKa of the weak acid.
