To learn how to calculate ion concentrations in an aqueous solution of a strong diprotic acid. Sulfuric acid, H2SO4, is a strong acid. Its complete dissociation in aqueous solution is represented as H2SO4?H++HSO4? A HSO4? anion can dissociate further by HSO4??H++SO42? but the extent of dissociation is considerably less than 100%. The equilibrium constant for the second dissociation step is expressed as Ka2=[H+][SO42?][HSO4?]=0.012 Part A Calculate the concentration of H+ ions in a 0.010 M aqueous solution of sulfuric acid....
