Nitric Acid Online. Too good to be true?

goldenchild;

Here are some links to pages on this forum that cover it.

Starting about halfway down this page, creading has a few posts on doing the "no water" method using battery strength (I've read that it is either 33% or 35%) sulfuric---

Lazersteve's links to his nitirc formula don't work on the last two, I think because they changed forum servers or software or something like that.

Also there is more discussion and yet another formula in this download---

Having a good supply of 68-70% nitric on hand, I do not need to make my own...

Steve,

Maybe its the amount of sodium nitrate used. In your method, how much sodium nitrate are you to use?

Reaction:

-Bring 100 mL of Distilled Water in a 500 mL pyrex beaker to 100 C
-Add the Nitre of your choice (202 gm K / 170 gm Na)
-Stir until Nitre is completely dissolved, let cool below boiling
-SLOWLY add 56 mL conc (96%+) Sulfuric Acid to Hot Nitre solution while stirring, DON'T allow the solution to boil!
-Allow solution to cool to room temp (DO NOT SKIP - VESSEL WILL SHATTER IF PUT ON ICE WHILE HOT!!!)
-When vessel reaches room temp (25 °C) put the vessel in the freezer or on a salt water ice bath
-Let stand until temperature of mixture reaches -5 °C
-Let stand at -5 °C until all percipitate settles
-Pour the COLD solution off into glass container with tightly sealed lid DO NOT POUR OFF ANY OF THE SALT IN THE BOTTOM!!!
-Makes ~160 mL ~50% HNO3

I tried 50 grams first because 170 just seemed like it wouldnt work. Seemed like there wouldnt be enough water to dissolve 170 grams. Then I actually tried 170 and when I poured the sulfuric in the mixture it turned into a cottage cheese like substance and when fully mixed it was like a milkshake(dont worry i didnt taste it). Is it possible the water wasnt hot enough to fully dissolve all the Na? It seemed to be totally dissolved. Or is that just way too much Na?

Thanks

170 gm is correct, that's 2 moles of niter.

Sounds like your reaction was normal. You should put the 'cottage cheese' in the cold bath at -5 C or lower for several hours and pour off the liquid after the salt settles.

Ive never had "Cottage Cheese" after dissolving my Nitrate... Mine dissolves to a liquid form and looks slightly yellow, once it starts to cool at room temperature the salts will start to form. I use Potassium N so maybe this is why mine doesn't look like Cottage Cheese.

Also, ive been bypassing the water method and just dissolving the Nitrate straight into the Sulfuric Acid (30% conc) or what ever it is. When i was dissolving with the water first i was getting a lot of the salts melting then reforming on the edge of my pyrex jug and it was a little messy for my liking until i saw a post here saying how to bypass the water method which turned out to be a lot easier and cleaner for me.

We recently had a Hydroponics store open near me. Remembering a post on the forum about some "PH Down" being Nitric acid, I asked the proprietor if he had, or had access to, PH Down that contained Nitric acid. He took my number and told me he would do some research. He found that he can get Technaflora brand PH Down, which is indeed Nitric acid, but he wasn't sure of the strength. I found their website and downloaded the MSDS which shows a strength of 5-10% Nitric acid.

Am I correct in assuming that this Nitric will work for dissolving my pile of header pins and floppy/ide connector pins from ribbon cable? I assume it will be somewhat slower than more concentrated Nitric.

Would it be faster than using the Muriatic acid I currently find at Lowe's for cleaning concrete?

 

[qst42know]

Did you happen to ask the price of the PH down?

 

[gold4mike]

Not yet - I was wanting to find out if it would be acceptable, price it online, then price it from my local guy to see if he gets it with other items (maybe via truck freight) and can save me money over the UPS HazMat upcharge. When all data is assembled I'll share with the forum so anyone else haveing a hard time finding inexpensive Nitric can benefit as well. You can find the manufacturer's website by Googling "Technaflora". I'll try to remember to call him and get pricing (my local guy) tomorrow from work.

so....has anyone been using this brand lately with great success both as a digester and in AR?

I haven't pursued that angle. I found GFS Chemical in Columbus, OH and they will express ship me up to 250 pounds for $65 so I bought 70% Nitric from them.

Today came in 6 Liters of Nitric , total costs 63 Euro

That is still $58 US per gallon.

Take a look at www.dudadiesel.com - they have 8 liter bottle of 67% Nitric acid for $185 (plus hazmat & shipping charges)

I ordered 2.5 liter Nitric acid from ArtChemicals.com - total charges were $114 inclusive.

Hope this is helpful

For the users in the E.U. specially in the Netherlands, Belgium, Germany, i want to advise this shop for the Nitric Acid and hydrochloric acid and other chemicals:

http://www.polycolor.be/nl/drogisterij/vloeistoffen/?searchbrand=81&cid=79

Nitric Acid 60%(40°BE) 5,00 Liter € 21,43, (Salpeterzuur)
Hydrochloric Acid 30,00 L ( 30%) € 51,30 (Zoutzuur)
Sulfuric acid 5,00 L (96%) € 26,38 (Zwavelzuur)

They have 2 companies, the one that has the chemicals, is the one in Helchteren.
They have only a limited supply on stock (order in advance cut be helpful), no questions asked, almost anyone can buy (no kids allowed to buy this for example), no ID required.

And hydrogen peroxide 35 % 25 liters € 27,82

http://www.melkveehouderijproducten.nl/melkstalbenodigdheden/melkmachine/waterstofperoxide-35-250.html
Maybe a bit too much hydrogen peroxide for me, but maybe it can help someone else.

Best Regards, Richard.
