Question

PLEASE only answer with COMPLETE, QUALITY answers. Thanks!

Given a diprotic acid, H2A, with two ionization constants of Ka2=5.56 times 10-11,calculate the PH and molar concentrations of H2A, HA-, and A2-, and A-2 for each of the solution below. the solution below. A0.176M solution of H2A 0.176 M solution of Na2A For part (a), treat H2A as a monoprotic weak acid with ka=ka1. For part (b), note that HA- is the intermediate from of the diprotic acid. For part (c), Treat A2- as a monobasic base with Kb=kb1=kwlka2.
