What is the K of the following reaction: HI ⇌ H⁺ + I^- , if [HI] = 0.15 M and the pH = 1.0?

Question

Quizplus · Accepted Answer

The equilibrium constant (K) for the reaction can be calculated using the given concentrations and the pH. The pH of 1.0 implies a [H+] concentration of 10^-1 M. Since HI dissociates into H+ and I-, and the products also involve protons, the concentration of H+ is directly related to the equilibrium. However, without the explicit concentrations of the products, we can't directly calculate K from the given information. The correct answer must be inferred or calculated based on additional information not provided in the question. Given the choices, the selection of 0.07 as the correct answer suggests an assumed calculation or approximation based on the given pH and [HI]. This might involve assumptions about the degree of dissociation of HI and the relationship between the pH and the concentrations of the products at equilibrium.
