UNIT 3PPA 2INTRODUCTIONOn electrolysing dilute sulphuric acid the hydrogen ions are reduced to hydrogen gas at the negatively chargedelectrode 2H HIGHERCHEMISTRY Quantitative Electrolysis UNI. 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. Pg. 658 - 660. Let’s talk about the lab…. In lab the reactions were spontaneous!. The solutions were arranged so that the electrons would move through the wires. Voltaic cells involving spontaneous reactions are typically used to run motors and perform other useful work. Medical Laser. What is Laser Hair Removal?. It’s a method of permanent hair reduction..
