Question

What happens at anode during electrolysis?

Answer 1

Hint :The method of decomposing ionic compounds into their constituent elements by sending a direct electric current through the compound in a fluid state is known as electrolysis. At the cathode, cations are reduced, while anions are oxidised.
By moving electric current into acidified or salt-containing water, for example, the original elements hydrogen and oxygen may be decomposed. Sodium and chlorine atoms can be separated from molten sodium chloride.

Complete Step By Step Answer:
Electrolysis is normally performed in an electrolytic chamber, which consists of a vessel with two electrodes (cathode and anode) attached to a direct current supply and an electrolyte, which is an ionic compound undergoing decomposition in a liquid phase or dissolved state in a suitable solvent.
The insertion or elimination of electrons from the external circuit causes an exchange of ions and atoms in the electrolysis process. Cations travel to the cathode as current passes, take electrons from the cathode (provided by the supply source-battery), and discharge into the neutral atom. The neutral atom is deposited on the cathode if it is solid, and it moves upwards if it is gas. The cation is reduced at the cathode in this reduction step. Around the same time, anions donate their excess electrons to the anode, where they are oxidised to neutral atoms. Anions emit electrons that pass through the electrical circuit to the cathode, completing the circuit.
A simultaneous oxidation reaction at the anode and a reduction reaction at the cathode are involved in electrolysis.
Since the anode is a positive electrode, negative ions are drawn to it. Negative ions lose electrons at the anode (they are oxidised). The final product is non-metal and often a gas, depending on the ionic content. Chlorine, bromine, iodine, and oxygen are other examples. (The cathode is the negative electrode.) At the cathode, reduction (electronic gain) occurs, and if the metal is less reactive than hydrogen, a metal is formed; if the metal is more reactive than hydrogen, hydrogen is produced.
