Faraday's Law of Electrolysis is a cornerstone in the field of electrochemistry. It explains how electric current can cause chemical reactions, particularly the deposition of substances on electrodes. Michael Faraday, a British scientist, formulated this law in the 19th century. His work laid the groundwork for modern electroplating, battery technology, and even the production of aluminum. Faraday's Law states that the amount of substance produced at an electrode during electrolysis is directly proportional to the quantity of electricity passed through the electrolyte. This principle has practical applications in industries ranging from metallurgy to electronics. Understanding Faraday's Law helps us grasp how energy and matter interact on a fundamental level.
