How to Make Pure Nitric Acid the Easy Way

Watch as Science Hideout demonstrates the 'easy way' to make red fuming nitric acid, using two readily available chemicals. The end product is concentrated and reasonably pure, even without distillation.

May I ask, what is this 'turbar' you speak off?

[ScienceHideout]

@Megorniph

A turbar is a little magnetic pellet that you use with a turplate. In other languages, it is called a 'stir bar'.

Is there any way of removing the dissolved NOx from RFNA without diluting?

[ScienceHideout]

@TheCrazyFinn

Yes. It is called vacuum distillation- and it is the organic chemistry nightmare. It is essentially a regular distillation, but all the gas inside the setup gets sucked up and out. This means your pure white fuming nitric acid will condense, and all the NOx impurities will be sucked up.

Can any other acid be used instead of sulphuric acid?

[ScienceHideout]

@einarilaatikko

Good question! Put simply, no. The sulphate ion is transferred to the sodium ion. Sodium sulphate (or bisulphate) will precipitate out of a cold solution. Stuff like sodium chloride probalby wouldn't.

This vid is named.. How to Make Pure Nitric Acid the Easy Way ..i think you have mistaken the word easy for long ,,lol ,,its much less messing about if you just boil sulfuric acid with a nitrate salt and precipitate the pure nitric acid in to a beaker surrounded with ice all in 1 go,,,

what about CuSO4?

[xoxoXoieoxox]

the phisicl reason the ice is harder to raise in temp. is at the molecular level the moliculs are locked in position in the ice and in the water it is easer to get the water molicules to move so it heats faster ilke wax in its hardend state a microwave has little efect on it but if its already liqud it heats realy fast in the microwave due to the moliculs are lose =3-

@Khamila1 Hm I thought it was the process that defined which one it was not the purity

[Khamila1]

@TheSolitaryTraveller red fuming is higher concentration, 95% or better. Yellow is that way because it has more impurities, in this case, nitrogen oxides. His is somewhere between 86% and 94% pure most likely.

you talk funny, but amazing video

[PyroPudding]

The reason the vacuum distillation takes out the NOx impurities is NOT because it sucks up the fumes it is because it lowers the boiling point of the nitric acid to a level that is below the decomposition point of nitric acid into NOx and water.
