WebIonisation energy is a measure of the energy needed to pull a particular electron away from the attraction of the nucleus. A high value of ionisation energy shows a high attraction between the electron and the nucleus. The size of that attraction will be governed by: The charge on the nucleus. Web25 mei 2024 · The acid dissociation constant is the equilibrium constant of the dissociation reaction of an acid and is denoted by K a. This equilibrium constant is a quantitative measure of the strength of an acid in a solution. K a is commonly expressed in units of mol/L.
