Question

In an acidic solution at 25^$\circ$C, which of the following is not true? A) [H₃O⁺] > 1.0 × 10^-7 B) [H₃O⁺] > [OH^-] C) [OH^-] < 1.0 × 10^-7 D) [H₃O⁺][OH^-] > 1.0 × 10^-7 E) [H₃O⁺][OH^-] < 1.0 × 10^-7

In an acidic solution, there is H+ present which can react with HSBUO or OH- to form water. Thus, [HSBUO][OH-] < Kw = 1.0 × 10^-14. From this, we can derive that [HSBUO][OH-] > 1.0 × 10^-14 / [H+][OH-] = 1.0 × 10^-14 / Kw = 1.0 × 10^14 since [H+][OH-] = Kw. Therefore, D is the only option that is true.
