Explain asymmetry effect and electrophoretic effect of strong electrolytes
Answers
An Ionic atmosphere is a theory that explains the conductivity behavior of solutions (electrolytic solutions), where one charged entity attracts an oppositely charged entity.
Asymmetry effect is the asymmetrical or irregular distribution of the ion cloud around an ion which occurs from the finite relaxation time when a voltage is applied. It leads to a decrease in the mobility of the ions. When a voltage is applied, the ions move to an oppositely charged electrode and drag the cloud of ions along with it causing the ionic atmosphere around the moving ion to be asymmetrical.
Electrophoretic effect is the tendency of the applied potential to move the ionic atmosphere which reduces the ionic motion in a solution. The attractive forces in between the solvent molecules and the ions cause the solvent molecules to be dragged along with the ionic atmosphere. The movement of the central ion is slowed down as it moves opposite to the ionic atmosphere, towards the pole.
