Orange Juice Clock   
(Movie/Animation, Audio/Visual (3))
In this demonstration a galvanic cell is made from the combination of a magnesium strip, a copper strip, and juice in a beaker. The current from this cell is used to drive a clock normally powered by a DC battery.
Oscillating Reaction: Briggs-Rauscher   
(Movie/Animation, Audio/Visual (3))
When a solution of malonic acid, starch, and manganese(II) ion is added to a solution of hydrogen peroxide, iodate ion, and sulfuric acid, gas bubbles form and the color of the resulting mixture oscillates periodically from colorless to amber to blue.
Electrical Properties   
(Movie/Animation, Audio/Visual (2))
Use of the conductivity meter and techniques for measuring voltage of electrochemical cells are demonstrated.
Electrochemical Series: Metal Trees   
(Movie/Animation, Audio/Visual (11))
A piece of metal (Cu, Zn, Ag, Cd, or Pb) is placed in an aqueous solution of a metal ion (Cu2+, Zn2+, Ag+, Cd2+, or Pb2+). In some cases the growth of metal crystals indicates that a chemical reaction has occurred.
Electrochemical Cells   
(Movie/Animation, Audio/Visual (10))
Techniques involved in measuring the voltage of an electrochemical cell and some common errors in constructing electrochemical cells are demonstrated.
Electrochemical Cells(ChemPages Lab)   
(Instructional Material (1))
Electrochemical Cells: this is a resource in the collection "ChemPages Laboratory Resources". The cell design described in this module includes two solutions connected by salt bridge (piece of string) and two electrodes (metal strips) connected to a voltmeter. The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source.
