Redox Reactions: Electrolytic cells 1: electroplating

Regular price $125.00 $0.00

Part of a comprehensive 9-part series exploring the chemistry of both galvanic and electrolytic cells, and their many important applications.

This program contrasts energy conversions in electrolytic and galvanic cells, then explores electroplating applications of electrolytic cells – including copper electro-refining – and the concept of competition at electrodes.  The related process of anodising is outlined. Faraday’s laws of electrolysis are explained, then applied to practical electroplating calculations.
