These experiments were carried out with rather high concentrations of hydrogen peroxide.

Some chemical reactions change temperature, change color, produce a gas, or make a solid from two liquids. Try this reaction and see what it does! Pour 1 tablespoon of hydrogen peroxide into a cup.

I. The reaction between iodide and hydrogen peroxide produces triiodide. The triiodide ions are reduced back to iodide by thiosulfate at a much faster rate, until the thiosulfate is consumed. Then the ...
