Electrolytic Cells and electroplating Low

In this video lesson, Mr. Scullion demonstrates a reacting mass problem involving ammonium dichromate. Try the problem out on your own prior to finding out the solution.

Here's well look at more details of electroplating. We'll talk about oxidation and reduction, anodes and cathodes. We'll write half reactions for the two processes that are happening in the electroplating cell. How does electroplating work? It is a process where you usually take an object made of one type of metal, and cover it with a thin layer of another type of metal. Usually, precious metals like gold, silver, or platinum are the metals that are electroplated. In an electroplating cell, electrons are removed from one of the metals, which is an oxidation process that happens at the anode. This causes the metal to develop a charge turn into an ion, and allows it to dissolve in the solution. Then, at the cathode, reduction takes place, and the metal ion turns into a neutral atom, and sticks to the surface of the other metal.

This chemistry lesson is titled How do Fuel Cells Work and will give a detailed explanation of the topic.

All about Galvanic Cells, which are also called Voltaic Cells. These are devices that use a chemical reaction to create electricity. Moving electrons create electricity, and electrons flow from the anode, the site of oxidation, to the cathode, the site of reduction. The galvanic or voltaic cell also includes a salt bridge, which helps to balance charge, and lets ions move between the two half cells. In this video, we'll talk about oxidation, reduction, cathodes, and anodes. We'll write redox half reactions for the two half cells, which show the gain and loss of electrons.
