Electrolysis is not a study in itself but rather a process or technique. Electrolysis is a chemical reaction that involves the use of an electric current to drive a non-spontaneous chemical reaction. It is often used to separate compounds into their constituent elements or to deposit certain materials onto a surface.
However, electrolysis can be studied as part of various fields, such as electrochemistry, chemical engineering, and materials science. These disciplines involve the scientific investigation and understanding of electrolysis, its principles, applications, and related phenomena. So while electrolysis itself is not a study, it is a subject that can be studied within the context of broader scientific disciplines.
