For the compound H2XO2, the acid dissociation constants are given as K1 = 8.09 x 10^-7 and K2 = 8.09 x 10^-11. A) For a 0.040 M H2XO2 solution, calculate the concentrations of H+, HXO2-, and XO2 2-. B) Calculate the pH of a solution made from 0.100 moles of Na2XO2 in 1.00 L of water. C) Sketch the titration curve which is expected when a solution contains 0.0100 moles of Na2XO2 and 0.0100 moles of NaHXO2 is titrated with 8.09 M HCl. Your sketch should indicate the volumes of titrant needed to reach the equivalence points.
