		Electrochemical Cells The operation of an electrochemical cell is shown with a laboratory model of a zinc-copper cell. Animation at the atomic level shows that differences in activity levels determine the effectiveness of the electrochemical cell.

		The Building Blocks of Electrochemistry Basic concepts of electrochemistry are introduced with the aid of a robot powered by an electrochemical cell. The chemical reactions that occur inside the cell demonstrate the principles of reduction and oxidation-the redox reactions-that produce the...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
		Electroplating The causes and results of electrolysis, a nonspontaneous reaction requiring a source of electrical energy, are shown through animation. We discover that studying the reduction potentials for each possible half-cell reaction enables us to predict whic...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
		Designing Electrochemical Cells This program shows how to build a super electrochemical cell, explaining the need for a standard half cell, how to predict the direction of the electron flow, and, finally, how a table of reduction potentials can predict the output of a cell.
