The ionic product equilibrium constant is
Correct answer: D. Kw
- A. Ka
- B. Kb
- C. Kc
- D. Kw
Explanation
The ionic product equilibrium constant, represented by Kw, is defined for the self-ionization of water. It is the product of the concentrations of H+ and OH- ions in water, typically at 25°C, where Kw = [H+][OH-] = 1.0 × 10-14 mol2/L2. Kw is unique to the self-ionization of water, whereas Ka and Kb are used for acids and bases, and Kc is a general equilibrium constant.
