Homework Answers
pH before any titrant is added = 1.8
pH at the midpoint of titration = 2.6
pH at equivalence point = 7.5
At equivalence point pH = pKa
7.5 = - log Ka
Ka = 3.1623 * 10-8
pH before any titrant is added = 4
pH at the midpoint of titration = 7.2
pH at equivalence point = 10
At equivalence point pH = pKa
10 = - log Ka
Ka = 1 * 10-10
