Classic chemistry experiments: electricity from chemicals

No comments

Test the tendency of various metals to form ions

Reactive metals form ions more readily than less reactive metals. This experiment illustrates the tendency of various metals to form ions. Two different metals and an electrolyte form a cell. The more reactive metal becomes the negative pole from which electrons flow.
