Yes. the fume hood is a given even though I can name a few students who would benfit from a good sniff of Cl2
. The reaction is actually quite gentle as the Cl2 is made by mixing HCl with KMnO4 so production of the gas is slow (no heat). I also do one with I2 crystals, Al and water. This is great, lots of red flame and purple smoke (yes in the fume hood
) but it does get very hot (i.e. melts the sand bed). I also do the thermite reaction (mix and run away
) on the back oval as well as several others. The do gooders have not killed chemistry entirely yet and the kids love it as it gets them out of yet another boring theory lesson. I think they really enjoy watching me sprint away from impending doom as well
.
