Question:

Arsenic acid (H3AsO4) has Kas of 5.65 x 103,1.75 x 107 and 2.54 x 1012. For a 0.1M solution of the acid, a) show that the pH is dominated by the products of the first ionization, and b) compare the concentrations of HAsO,2 if you started with a 0.1M solution of NaH2AsO, instead of the original 0.1M H3AsO
