Description of experiment
Below follows a plain text transcript of the selected experiment.
Needed compounds:
-----------------
sulphur : S8
potassium bromate : KBrO3
Class:
------
elem=Br,S
redox
Summary:
--------
When potassium bromate and sulphur are mixed, then a very dangerous mixture
is created. This mixture, when ignited, produces an intensely bright flame.
Description:
------------
Carefully mix a small amount of potassium bromate and a similar amount of
powdered sulphur and heat with a flame: An intense bright purplish white
flame/flash is produced and the mixture deflagrates in a fraction of a
second. No noticeable sound is produced, the reaction is not explosive.
BEWARE: This must be done with minute quantities of potassium bromate and
sulphur (not more than a pinch on the tip of a knife)!
