Expert Answer
Ionization is the process of converting an atom or molecule into an ion by adding or removing charged particles such as electrons or ions. when ionisation occurs during equilibrium a constant is formed which is called ionisation constant.
let us consider the ionisation of an acid:
For the reaction in which the acid HA dissociates to form the ions H+ and A-, where Ka is ionisation constant:
HA
H+ + A-
H+ + A-| Ka = | [H+][A-] |

[HA]
