I found this cleaner at Home Depot about a year ago. I as well wondered about the concentration of HNO3. I did find their MSDS. It states 15-35% by weight for both Nitric Acid and Phosphoric acid (that is to say each would contribute that much, not a combined 15-35%). I struggled to find some way to extract the HNO3. I thought if I tried to distill it, it would break down the HNO3. Thanks for showing us you can distill this acid out of this mix successfully.
Hey thanks for the mention! I'm glad my video was an inspiration for you :) Great video - I like all the different processes you went through to end up with a good product. I don't have either phosphoric or nitric acid, so this would be pretty useful for me. I think I've seen a similar product at my hardware store, might need to look into it!
Are you sure it is white fuming nitric acid? It looks more like a yellow or red fuming nitric acid. I was under the impression that white fuming nitric acid could only be created under significant vacuum to prevent any NOx contamination. I believe if there is any NOx dissolved in the acid it is classified as red although the name yellow has often been used to describe it.
Why not break they azeotrope in the first distillation by adding sulphuric acid then. Also have you thought of packing the tube and doing fractional distillation?
Why didn't you use a packed distillation column to avoid the foaming issue? Could you have used Anhydrous magnesium sulfate as a drying agent to remove the excess water rather than the laborious task of re-distilling it? Interesting experiment however.
I like the video but I would have added calcium nitrate to the stock solution. This would ppt out calcium phosphate and increase the amount of HNO3 available. What do you think?
Otherwise, nice video. This product is available to me and I have looked at it more than once. I may end up buying some now, as I rather dislike using up sulfuric acid to make my nitric (which I don't particularly use much of anyway, but I'm running low).
Instead of the copper, you could have looked up the MSDS.Find the product on Home Depot's website. The MSDS is under the "More info" tab at the bottom.
Using fuming as an estimation of concentration is not particularly reliable. My 90% nitric fumes profusely and white fuming nitric acid refers specifically to anhydrous or nearly anhydrous HNO3. Furthermore, the 16M you quote is for azeotropic nitric acid. Lastly, I think you're adding an extra r when you pronounce titration (tie-tray-shun).
-@UC235 caught me being lazy.. It's density is 1.49 g cm-3,Pure Nitric acid is 1.51 g cm-3 thus it should be 98.6%. The MSDS is the best way... I was really trying to treat it as an "unknown" to show a way of roughly determining the amount based on limited info.
Speaking on videos is not my strong point... I talk way to fast and add r's were there are none. ;-) I am always amazed at how you can do your videos in one take.
@myst32YT nice. r u southern or live down south cause i am northern but i moved down south and i also pur r's where there arnt eney. btw this video helped me out on makeing nitric acid easy and cheap. im to lasy to wait 3weeks to get nitric acid in the mail
@myst32YT They're never one take. Especially the intro. Sometimes that is 20 takes. But, I know when I screw up, and stop recording. Once I hit the mixing chemicals part, there's no going back. Any mistakes I make are creatively edited out or I'll add text correcting myself. As for the actual concentration, check out the link in the description of my nitric acid's video. The exact temperature the density measurement is taken at is pretty critical and more significant figures is better.
@UC235 Nice chart!! Will retake measurement again tomorrow. Your right a couple degrees makes a major difference. haha More sig figs equals more money. Thanks for the advice, and your time.
@myst32YT I just have a series of small volumetric flasks, class A. They were not very expensive . With a larger flask, the innacuracy of your scale becomes less important. I have 5,10,25,50, and 100ml. I also have a total immersion mercury thermometer with large 1-degree increments that I can very accurately read to measure room temp. Allow significant time for the sample to reach equilibrium temperature. Measure the flask empty and full, subtract, divide by the volume, and you're done.

If you ask for an MSDS they will give one to you and you can see the % content of each.

@michalchik You would need to use a large amount of acid making it impractical.

Should have just used the MSDS for it, would tell you it is between 15-35% nitric acid by volume.

try installing a metal mesh in the narrow part of your flask- this is a very common way to battle foam in chemical industry
