Lab experiments are a way to help students interact with the principles of
chemistry and understand how the information from their textbook looks in
real-life scenarios. In some places, high school teachers mostly use quick
demonstration such as the Ammonium Dichromate self-decomposition, commonly
called the" volcano". Another popular high-interest experiment is using
different salt solutions to create different chemical reactions and
different colored precipitates such as lead iodide, silver chloride,
barium sulfate and silver chromate. Most of the chemicals which left over
in these experiments are toxic and the way of disposal is very important.
Aslo one should be very careful for the kind of gas which produce
during the experiment. I have written books for experiments in high school
and I study hard for each one to be safe and fun. You may
