As usual today, I'll show you one very interesting chemical experiment
Look at this black granules, this is palladium on carbon.
This form of palladium is used as a catalyst and also absorbs hydrogen very well
For this experiment, we will use Palladium on carbon powder,
Which means these granules must be grinded in the first place
Next we need hydrogen that we will get during the reaction of lithium hydride with water
To be completely honest, it is better to use dry hydrogen from a gas cylinder for such an experiment,
so let's just burn the one that we've got in this reaction.
I attached a nail to the balloon so that the balloon will not fly away
It could, because hydrogen is lighter than air.
And for a more powerful blast, I'll increase the oxygen concentration around the ball.
Now we need to cool down the test tube with a powder of palladium on carbon to low temperature in order to do that
In order to do that I will use a special vessel that I pour liquid nitrogen in,
dip the tube
and put a balloon filled with hydrogen on it.
Palladium on carbon has already begun to absorb hydrogen.
However, you still have a chance to notice the balloon's volume dropping down a little.
What a bummer our balloon has blown out
It happened because some of the powder got inside the balloon when I shake the tube
And when hydrogen was absorbed the Palladium carbon powder was heated to a high temperature
Which damaged balloon's rubber
Okay, let's repeat all the actions up until the moment the balloon blew out
Now let's remove the balloon from the test tube and wait a few seconds to make sure all the hydrogen left the tube
And now the climax of the experiment!
We add a drop of liquid chlorine to our palladium-carbon powder
Pretty awesome, huh?
