Unit 8.3 - Weak Acid and Base Equilibria
At 57:55, I give the answer to part b (ii) of the practice free-response problem, and I used the wrong Ka value. I used 1.35 x 10^-5 when I should have used the Ka value we just determined...1.4 x 10^-4. When you use the correct Ka value, the final pH is 2.28. My apologies!
