The ionic product of water, Kw, is the product of the concentrations of hydrogen ions (H+) and hydroxide ions (OH-) in water at a given temperature. It is a constant value at a given temperature, typically 25°C, and has a value of 1.0 x 10^-14 in pure water. Kw = [H+][OH-].
The unit for the ionic product of water is mol2/L2.
The unit of the ionic product of water is mol²/L². It represents the equilibrium constant for the ionization of water into its constituent ions, H⁺ and OH⁻.
The ionic product for water is expressed as Kw, which is equal to 1.0 x 10^-14 at 25°C. This value represents the product of the concentrations of hydrogen ions (H+) and hydroxide ions (OH-) in pure water.
The solubility product constant (Ksp) of sulfuric acid (H2SO4) is not typically provided because it is a strong acid that dissociates almost completely in water. The ionic product of sulfuric acid would involve considering the dissociation into H+ and SO4^2- ions.
The ionic product constant of water, Kw, is temperature dependent because the dissociation of water into hydronium ions (H3O+) and hydroxide ions (OH-) is an endothermic reaction. As temperature increases, more water molecules dissociate into ions, leading to an increase in the concentration of H3O+ and OH- ions, thus affecting the value of Kw.
