Ionic Equilibrium
H2O is the medium of biological systems one must consider the role of this molecule in the dissociation of ions from biological molecules. Water is essentially a neutral molecule but will ionize to a small degree. This can be described by a simple equilibrium equation:

 H2O ↔ H+ + OH–
This equilibrium can be calculated as for any reaction:
Since the concentration of H2O is very high (55.5M) relative to that of the [H+] and [OH–], consideration of it is generally removed from the equation by multiplying both sides by 55.5 yielding a new term, Kw:
Kw = [H+][OH–] This term is referred to as the ion product. In pure water, to which no acids or bases have been added:
Kw = 1 x 10–14 M2 As Kw is constant, if one considers the case of pure water to which no acids or bases have been added:
[H+] = [OH-] = 1 x 10–7 M This term can be reduced to reflect the hydrogen ion concentration of a…
