answered-by-expert Expert Answer

It is the fraction of the total number of molecules, which dissociate into simpler ions i.e.,

If a molecule of an electrolyte when dissolved in a solvent dissociates to give n ions and a is the degree of dissociation and  Van't Hoff factor = i then

n = Number of ions provided by one formula unit.
