Electrolytic Cells: Construction and Electroplating

There are two types of electrochemical cells. One is the electrolytic cell, which uses electrical energy to drive a nonspontaneous reaction. In this type of cell, electrical energy is supplied from an external power source. The other type of cell is the galvanic cell, which uses a spontaneous electrochemical reaction to generate electrical energy.

What Is A Cell? By structure, it is a porous membrane (with pores) which permits the movement of selective substances in and out of the cell. Besides this, the cell membrane also protects the cellular component from damage and leakage. It forms the wall-like structure between two cells as well as between the cell and its surroundings.

Difference between Galvanic Cells And Electrolytic Cells

A galvanic cell is an electrochemical cell in which spontaneous redox processes occur allowing the continuous flow of electrons through the conductor, whereas, in an electrolytic cell, the redox reactions are influenced by an external source of current. Know more differences between galvanic cells and electrolytic cells by visting us.

Electrolytic Cells and Electrolysis

Electrolysis is the name given to the process that occurs in an electrolytic cell, where an electrical current is used to start a non-spontaneous reaction. Electrolysis, and thus an electrolytic cell, is often used in real applications for separating a substance—two common examples are the decomposition of NaCl and of H 2 O. We will look at ...
