In this video, Nitric acid is distilled with sulfuric acid to concentrate it. Afterwards, the concentrated Nitric acid is purified by distilling under vacuum.
Properties of nearly 100% Nitric acid are demonstrated

  • yeah what is the ratio of nitric to sulfuric you used?

  • @CHEMIST674 This is my guess, say you have 70% nitric acid and you have 500ml of it that you are wanting to distill. Just add 1000 ml of 98% sulfuric acid. So just add twice as much sulfuric acid as the nitric acid.

  • hvor mye vann tar 100ml H2SO4 opp ?

    Jeg skal destillere fra 62 % HNO3

    Takk for svar

  • It's been a while since we talked! N vids are great as I remembered. As for this one, could u remind us the ratios, for a good distillation rate??

  • could i use this method to further concentrate 90% nitric acid and would ther be any changes or could i just do the same thing

  • @hobomnky watch nurdrages video to see..

  • @mabakken so you are using H2SO4 as a drying agent?? usually P4O10 is used to dry the azeotrope

  • You need to add boiling chips.

  • @mabakken How did you know how much H2SO4 to add?

  • nice video! i just got 25% nitric (highest i seem to be able to get) and want to make aqua regia to dissolve gold, i will try this, only thing is my sulphuric is only about 20%, do you think that would work or would there be too much water for it to suck out the water from the hno3 and give it a desired azeotropic phase?
