Question

Your friend at Podunk U. urgently emails asking if you remember any acid–base chemistry. His problem is that for his final organic lab problem he needs to report the pK_a of his acid. He did the pH titration, but only wrote down the following data for the titratant volumes: V = 14.27 mL; pH = 4.73. V_{equivalence point} = 22.43 mL. What is the pK_a of the unknown acid?

a) 4.0

b)3.5

c)4.5

d)4.8

e)4.9

Answer 1

OPTION is the correct option...

Best of Luck;

Thank You:-)
