Electrochemical Cells

Electrochemical cells are systems that convert chemical energy into electrical energy or use electrical energy to drive chemical reactions. They consist of two electrodes in contact with an electrolyte, where redox reactions enable electron transfer. Most electrochemical cells include two half-cells connected by an external wire for electron flow and a salt bridge for ion flow. The salt bridge contains an electrolyte solution and maintains charge neutrality by allowing ions—not electrons—to...

Concentration Cells

A concentration cell is an electrochemical cell in which the emf arises from a difference in concentration of a species between two half-cells. Unlike galvanic cells, where electrical energy comes from a chemical reaction, the driving force here is the transfer of matter from a region of higher concentration to lower concentration. The overall process is therefore physical in nature. A classic illustration is a cell made of two chlorine electrodes operating at different chlorine gas...
Processes at Electrodes01:30

Processes at Electrodes

The electrode interacts with ions in the electrolyte solution at its interface. The rate of oxidation and reduction depends on the speed at which electrons can transfer through this interface. As ions attach to or leave the electrode surface, the electrode acquires a charge, and an electrical potential forms across the interface, making the process more difficult to reach equilibrium. The charge on the electrode affects the local ion concentrations in the solution, though thermal motion...
