Hypoiodous acid, HIO, has an acid dissociation constant of Ka = 2.3 x 10-11 .

a) What is the useful pH range of a buffer prepared from hypoiodous acid and its conjugate base, hypoiodite?

b) Determine the pH of a solution prepared by mixing 25.0 mL of 0.212 M hypoiodous acid with 30.0 mL of 0.126 M NaOH (you may assume that the volumes of the solutions are additive).

c) What mass of HCl(g) can be added to the solution in part (b) before it is no longer a buffer? Ka (HCl) = 4.5x10^-7
