Study Notes

Electrochemistry

Electrochemistry is the branch of chemistry that deals with the relationship between chemical reactions and electricity.

Conduction Mechanisms

Electrolytic conduction is the process by which an electric current flows through an electrolyte, a substance that dissociates into ions.
Mechanism of electrolytic conduction: ions in the electrolyte move towards the oppositely charged electrode, facilitating the flow of electric current.

Types of Conductors

Metallic conductors: allow electric current to flow through the movement of electrons, not ions.
Electrolytic conductors: substances that dissociate into ions, allowing electric current to flow through the movement of ions.

Electrolytic Conduction

When an electric current is applied to an electrolyte, ions move towards the oppositely charged electrode.
At the anode (positive electrode), negatively charged ions (anions) such as Cl─ move away from the anode, allowing the electric current to flow.
