PPT-The Chemistry of Copper Electrolysis

Objectives Apply basic chemistry principles to understand the process of electrolysis Understand how electrolysis is used in the processing of copper ores Electrolysis Uses an electrical current to move ions in an electrolyte solution between two . The purpose of electrolysis is to split up ionic compounds using electricity to produce useful products.. Electrolysis is used a lot in industry and is a multi-billion pound industry. It is used to produce all of the Copper, Aluminium, Chlorine and Caustic Soda (sodium hydroxide) that we use today as well as to produce gold and silver plated jewellery and chrome-plated taps and bicycle parts. LQ: What happens at the electrodes?. Learning outcomes. I can describe electrolysis as the decomposition of an electrolyte with an electric current – Grade B. I can describe the changes at the electrodes during electrolysis – Grade A. Electrolysis . Process by which an electric current is passed through a substance to cause a chemical change.. The chemical change is one in which the substance loses or gains an electron.. Electrolysis. Mr. Chapman. Electrolysis.
