Question

what are electrolysis?

please don't delete my questions The brain please ​

Answer 1

• Electrolysis is a chemical transformation induced by passing an electric current through a material.
• When a material loses or gets an electron, it is called a chemical change (oxidation or reduction).
• An electrolytic cell is a device that consists of positive and negative electrodes that are kept apart and dipped into a solution containing positively and negatively charged ions.
• The substance to be changed might be the electrode, the solution, or it could be dissolved in it.
• The negatively charged electrode (cathode) receives electric current (i.e., electrons); solution components go to this electrode, mix with the electrons, and convert (reduced).
• Neutral elements or new compounds might be the end result.
• The solution's components also move to the opposite electrode (anode), surrender their electrons, and are converted (oxidised) into neutral elements or new molecules.

Answer 2

The production of a chemical reaction by passing an electric current through an electrolyte is known as electrolysis.

Explanation:

In electrolysis , positive ions migrate to the cathode and negative ions to the anode . The reactions occuring depend on electron transfer at the electrodes and are , therefore, redox reactions. [ redox reaction : when one reactant gets oxidised while the other gets reduced during a reaction ] . At anode , oxidation occurs while at cathode , reduction takes place.
