Being simultaneously basic and acidic, water undergoes autoprotolysis, also called self-ionization:
The equilibrium constant is
H3O+ in these equations is general simply written H+. In pure water and in solutions that do not give any additional source of H+ or OH- both ions have molar concentrations exact to 10-7. Addition of an acid decreases [OH-] and hence increases [H3O+]; addition of a base has the reverse effect.
The pH scale is defined by
Neutral water has a pH of 7, acidic solutions have lower values of ph (typically 0-7), and basic solutions or alkaline higher values (7-14). In alkaline or basic solutions [OH-] is thus greater than [H+].
Strong and weak behavior
The equilibrium constant of the protolysis reaction
is known as the acid dissociation constant (Ka) of HA or the acidity constant:
It is often expressed as a pKa value, described as
amphoterism of methanol Compound A is much more basic than compound B (charge effect). By the element effect, C is much more basic than A; this follows from the fact that if we

The amount of energy released when one mole of bonds are formed among the corresponding gaseous atoms is known as Bond energy.
The table below gives intrinsic viscosity values determined by viscometry and weight- average molar mass values determined under the same conditions by static light scattering.
