When two oppositely charged electrodes are immersed in a solution, positively charged ions are attracted to the negative electrode and gain electrons. The negatively charged ions are attracted to the positive electrode and release electrons. What would be the net effect of this on conduction of electricity through the solution?

Kendall Daugherty · Answer 1

conductivity of solution is reduced.

Explanation:

When two oppositely charged electrodes are immersed in a solution, positively charged ions are attracted to the negative electrode and gain electrons. The negatively charged ions are attracted to the positive electrode and release electrons.

Due to the process mentioned above, the negatively charged ions are accumulated at the positive electrode and the positively charged ions are accumulated at the negative electrode. This accumulation prevents further attraction of ions at oppositely charged electrodes because the incoming ions face repulsion from already accumulated ions at electrodes. Further, it creates an emf acting in opposite direction. It reduces the current through the solution. Hence conductivity of solution is reduced.
