User:GetLinkPrimitiveParams/Speciation (chemistry)
Speciation is the distribution of an element amongst defined chemical species in a system
Especially by ions, the most chemical elements can be present in different states. For example, water can be present as the liquid molecule H2O, but also as ions H3O+ and OH-.
For ions, the distribution of these speciation can be predicted with the equilibrium constant (K). For pure water, this constant is:
![{\displaystyle K=10^{-14}=[H_{3}O^{+}][OH^{-}]}](https://wikimedia.org/api/rest_v1/media/math/render/svg/21424520db5ffb427afa76687d0fc2e4a4405c1c)
