19. For the equilibrium that exists in an aqueous solution of nitrous acid (HNO2, a weak acid), the equilibrium constant expression is: (A) \( K = \frac{[\text{H}^+][\text{NO}_2^-]}{[\text{HNO}_2]} \) (B) \( K = \frac{[\text{H}^+][\text{N}^{3+}][\text{O}^{2-}]^2}{[\text{HNO}_2]} \) (C) \( K = [\text{H}^+][\text{NO}_2^-] \) (D) \( K = \frac{[\text{H}^+]^2[\text{NO}_2^-]}{[\text{HNO}_2]} \)
