SUMMARY

Resistance in electrolytic solutions arises from the collisions between ions and the solvent molecules, primarily water, as they move under the influence of an electric field. This phenomenon adheres to Ohm's Law and Pouillet’s Law, indicating that resistance is a function of the medium's properties and ion concentration. The repetitive acceleration and deceleration of ions lead to energy loss, manifesting as resistance. Understanding the molecular interactions in electrolytic solutions is crucial for grasping the underlying mechanisms of electrical resistance.

Hi!

So I know that in electrolytic solutions current is transferred via ions, but I don't understand where the resistance comes from.

I know that electrolytic solutions follow ohms law and Pouillet’s Law, but I do not understand what is actually going on that causes resistance.

I understand that in metals at an atomic level there is a a lattice like structure of ions in a pool of loosely bonded valence electrons. Voltage accelerate these electrons. However, these accelerated electrons collide with the ions in the conductor, loosing energy. This repetitive acceleration and deceleration is what causes electrical resistance.

But I do not understand what the equivalent is in electrolytic solutions.

Would anyone be able to point me in the right direction? I don't need you to give a full explanation, just even a reference to the type of thing I should be looking up.

Ions collide with water molecules (or whatever medium they are in).
