Introduction:-
So hey there, I am back again with new post on my blog which is about making colourful gases. Let me make it clear for you that here I am not talking about colourful smokes but actually some gases involving chlorine, nitrogen and some other chemical compounds.
Let's Begin:-
So here I am going to tell you some chemical reactions which I learned in school and I found them really interesting.
Making green gas:-
This one is a bit Spooky kind of reaction.
For that you need a salt of chlorine, for example sodium chloride, potassium chloride or any other kind of metal chloride. Put that salt into a petri dish or a test tube if you have it and add concentrated sulphuric acid and a bit of manganese oxide. Heat that for a while and you will see a green gas with a really very pungent smell which you are not supposed to smell.
So here is how the chlorine gas looks like:-
Brown gas:-
So we are done with green gas and now let's move on to another colour which is brown. Now this is another toxic gas which you would probably never want to smell. We are talking about Nitrogen dioxide.
So to start with, take a test tube and put in it any nitrate salt, and add Concentrated sulphuric acid and heat it for a while. After that quickly add some copper pieces of copper turnings and you will see a brown gas coming out of the test tube.
Along with it you will see that the copper turnings start to vanish making the solution bluish green, which is also a magnificent thing to see.
The reaction looks like this:-
2Cu(NO3)2 →2CuO + 4NO2 +O2
Where Cu(NO3)2 is that blue solution.
You should never smell this gas as this is highly toxic.
And here is the result:-
White gas:-
Although white is a symbol of peace, If you smell this gas you can easily rest in peace, so DO NOT SMELL THIS GAS EVER. Things needed to create this gas are easily available. You need to set a test tube and put in it some amount of ammonium salt, like ammonium chloride or something like that. Add Sodium hydroxide to it and then heat it. Take any glass roddipped in dilute hydrochloric acid and bring it near the test tube. You will see some white fumes of Ammonia that can go straight into your nose and burn your nasal cavity, so don't try to smell that. You can even put a drop of HCl on the wall of the test tube and it will keep on creating the fumes untill the solution cools down.
And this looks like:-
