Overview

Electrolysis is the process in which electrical energy is converted into chemical energy. An electrolytic cell is the device used for this process. In an electrolytic cell, a direct current passes through an electrolyte in fused form or in aqueous solution, causing chemical changes at the electrodes

Key Concepts

Electrolytes conduct electricity in the fused

Electrolytes conduct electricity in the fused state or in aqueous solution because they contain free ions. Strong electrolytes dissociate almost compl

Electrodes are metal plates or graphite

Electrodes are metal plates or graphite rods dipped in an electrolyte. The anode is the electrode where oxidation takes place and is connected to the

Cations are positively charged ions formed

Cations are positively charged ions formed by loss of electrons. Anions are negatively charged ions formed by gain of electrons. During electrolysis,

Oxidation is loss of electrons

Oxidation is loss of electrons and reduction is gain of electrons. Oxidation occurs at the anode and reduction occurs at the cathode during electrolys

An electrolytic cell converts electrical energy

An electrolytic cell converts electrical energy into chemical energy through electrolysis. An electrochemical cell converts chemical energy into elect
