Cells

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.

This video introduces electrolytic cells and electroplating.

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.

This video outlines how a voltaic cell or a galvanic cell works and how you can find the voltage between them and capture the flow of electrons through a wire.
