12.81b (6th edition)

In the solution manual, it says that Ka2 can be ignored. But Ka2 is larger than Ka1/1000, so wouldn't you have to do another ICE table using Ka2?

You would only have to carry out an ICE table for Ka2 if you are focusing on the second deprotonation of that acid; we work on the first and second deprotonations separately.
