Electrolysis

Electrolysis is the process of passing electrical current (direct current) through a solution or molten ionic compound, to decompose electrolytes.This separates the ions, and elements will be discharged at the electrodes.Inert electrodes should be used, otherwise they will react with the solution/products.

Electroplating C2

2019/6/19Electroplating uses electrolysis to coat the surface of one metal with another metal. The negative electrode is the metal object you want to plate and the positive electrode is the pure metal you want it to be plated with. You also need electrolyte to contain ions of the

Using Electrolysis

You can use electrolysis to coat one metal with another. This is called electroplating. Electroplating is used a great deal in industry, for example; chrome-plating car bumpers. If you wanted to coat a nickel vase with silver, you would set the vase as the cathode and

Electrolysis REVISION (GCSE)

2019/1/16This is a topic which is almost guaranteed to be on the GCSE paper every year and therefore a student's ability to achieve good marks on this topic will have a big impact on their overall success. The lesson looks at the electrolysis of both molten salts and aqueous solutions and guides students through predicting the products at each of the electrodes as well as writing half equations to

Electrolysis

The half equations for electroplating reflect this and are not the same as the half equations for electrolysis with inert electrodes. In this experiment the electrodes are inert so they are not taking part in the reaction, but the negative electrode is still being covered with a metal, as in electroplating, and that can cause confusion.
