Hydrogen Peroxide Peroxide Decomposition and Vinegar/Baking Powder with a Flame
Transparent container 1
Transparent container 2
40 ml of Hydrogen Peroxide (H202)
40 ml of Vinegar (CH3COOH)
5 ml of yeast (fungi)
5ml of Baking Soda (NaHCO3)
Matches
Skewers
PART ONE: Hydrogen Peroxide/Yeast reaction in a flame. You might want to do this in a sink 'cause it can get pretty messy.
Take the yeast and pour it in the first transparent container.
Now shake it up.
The column of bubbles should start rising
That's oxygen coming out. 2H2O2----->2H2O + O2
Now time to play with fire :)
Strike a match
Light the skewer with it.
Let the skewer burn out
Now stick the flaming part of the skewer into the column of bubbles.
Boom!
Now for the Vinegar/Baking Powder reaction... this is a VERY commonplace experiment but it's only cool when there's fire involved :)
Take the vinegar and pour it into Transparent container 2
Now take the Baking soda and pour it too
They should start bubbling. However, unlike the H2O2, this releases CO2 instead of O2. H2CO3--->H2O+CO2
Fire time again :)
Strike a match
Light the skewer again.
This time don't let the flame burn out... instead put it near the opening of the bubbling vinegar/baking powder and the flame stops burning because fire burns O2 but the CO2 is smothering it and therefore it can't burn anymore.
