Question

Write ionization equations and acid ionization constant expressions for each acid. (Acid ionization expressions take the general form: Equilibrium expressions take the general form: Keq = [C]c / [A]a . [B]b.. Use the lowest possible coefficients. Include states-of-matter under SATP conditions in your answer.)

(a) HClO2
(b) HNO2
(c) HIO

Answer 1

(a) HClO2 <=> H+ + ClO2-
Equilibrium expression is
Keq = [H+][ClO2-] / [HClO2]

(b) HNO2 <=> H+ + NO2-
Equilibrium expression is
Keq = [H+][NO2-] / [NO2]

(b) HNO <=> H+ + IO-
Equilibrium expression is
Keq = [H+][IO-] / [IO]
