Can someone explain the more dilute the solution is (acid solution) the greater the degree of ionization? Can someone explain the more dilute the solution is (acid solution) the greater the degree of ionization? Solution Degree of Ionisation means no. Of ions increase. And degree of Ionisation is directly proportional to the degree of disassociation more will be the dissociation of solution more will be its no. Of ions . On dilution the degree of disassociation increase because water provides energy for dissociation of acid and thus degree of ionisation increase with dilution . .
