Question
How is the total [H3O*] of a O.050 M aqueous solution of sulfuric acid,
H2SO4, determined?
O H2SO, is polyprotic, so ignore Ka1, and use only Ka2 to solve for the
[H3O*)
O Since it is strong acid, the total [H3O*] is equal to 0.050 M.
O First, [H3O*] = 0.050 M, then use K2 to solve for the additional
H30*] from the second ionization
O Make use of both Ka1 and K22 and solve the quadratic formula.
