Process where water dissociates to form H+\text{H}^+H+ and OH−\text{OH}^-OH− ions
H+\text{H}^+H+ (hydrogen) and OH−\text{OH}^-OH− (hydroxide)
Ionic product of water
Kw=[H+][OH−]K_w = [\text{H}^+][\text{OH}^-]Kw=[H+][OH−]
1.0×10−141.0 \times 10^{-14}1.0×10−14
1.0×10−71.0 \times 10^{-7}1.0×10−7 M
KwK_wKw increases with temperature
Endothermic, ΔH=+55.8\Delta H = +55.8ΔH=+55.8 kJ mol−1^{-1}−1
Greater than 1.0×10−71.0 \times 10^{-7}1.0×10−7 M
Less than 1.0×10−71.0 \times 10^{-7}1.0×10−7 M
Inverse: one increases, other decreases
Always equals KwK_wKw at that temperature
