Howdy guys! Now the style of video and the
channel will be of a better quality and the
unique chemical experiments will be the more refined
In one of the previous video I showed you reactions with sodium peroxide
and today I will
introduce you to its older brother
it is potassium superoxide
superoxide of potassium is a yellow solid like sodium
peroxide but much more reactive
while sodium peroxide on reactions with water formed hydrogen peroxide
potassium superoxide besides hydrogen peroxide
also forms oxygen
potassium superoxide is using in chemical oxygen generators
like canisters for rebreathers for fire fighting and mine rescue work
This application is based on the following chemical reaction
For demonstration we have assembled such a simple equipment
in a U-shaped tube filled with potassium superoxide
carbon dioxide will be obtained from
the chalk and HCl
look how potassium superoxide loses
yellow color and turns into white
carbonate producing oxygen which can be
detected with a smouldering wood
okay let's do some cool chemical
reactions with potassium superoxide
as you like it I know ;)
Potassium superoxide reacts violently with many organic substances
and very effectively with nitromethane
with acetic acid sodium peroxides reacts with inflammation,
but can potassium superoxide ignite formic acid?
Spoiler: NO
The reaction with formamide is not so fast
actually fast, but it is necessary to wait for the induction period to pass.
you can observe a violent reaction with
2,4-dinitrophenylhydrazine
it is necessary only to add a few drops of
water to accelerate it
In fact, potassium superoxide ignites many organic substances, I showed only a few of them
Inorganic time!
reaction with carbon disulfide
if you have whatched so far you will see now
a beautiful chemical reaction between
potassium superoxide and phosphorus pentachloride
such a reaction deserves a like
I can already anticipate how you ask in the
comments to perform a reaction of a
potassium superoxide with decaborane
So on your request it will be the next reaction.
thanks for watching don't forget to
subscribe to the channel and leave the
comments about the chemical substances and reactions
would like to see.
See ya next video
