Several of my students are having problems with this problem, and I do not like the way that Sapling worked this problem. The solution states that that the acid and 2nd conjugate base react to produce intermediate, ie H2A + A^2-^ <----> 2 HA^1^ then H2A +...

Figured it out. H2A <--> HA- + H+ K1 HA- <----> A2- + H+ K2 H2A <--> HA- + H+ K1 A2- + H+ <-----> HA- 1/K2 (not a Kb because not forming OH-, merely flipping the K2 expression.) H2A + A2- <---> 2 HA- K' = K1/K2 plug in the K values, K' = 2.2 x 10^4. VERY...

The answer is 160.
