SUMMARY
The equilibrium constant for the dissociation of water (KH2O) is derived from the reaction H2O <===> H+ + OH-. The dissociation constant is mathematically expressed as K = [H+][OH-], where the concentration of water is considered constant and not included in the expression. Conductivity measurements of pure water can be utilized to correlate the concentration of ions produced during dissociation, providing a practical method for determining KH2O. This discussion emphasizes the importance of understanding the underlying chemical reactions and their equilibrium constants.
