Since you live in Quebec, go to Home Hardware and buy Liquid Lightning drain opener. That is what I use and have never had a problem. If you dont trust the fertilizer nitrate you have, and cant find a substitute, go to Shoppers Drug Mart and get one package instant cold packs that they sell for $9.99.
Jul 6, 2023. #24. Making your own Nitric Acid is a dangerous, costly and time consuming endevour. The starting reagents will set you back~ $10 for the KNO3 and ~$20 for the H2SO4. The Lab Equipment is another discussion. After 2-3 hours, the yeild is about 1 liter and you just took some major health risks.
If you bought the "LabChem LC178002 Nitric Acid Solution, 0.1N (0.1M), 1 L Volume" then the concentration is in the name. 0.1M means 0.1 mol/liter. A mole of nitric acid weighs 68g, so that bottle contains 6.8 grams per liter. The 68% concentrated acid is around 15M in concentration, that bottle contains nitric acid diluted 150 times.

The application fee for the permit is a little over 80 USD and there is no guarantees that you will get the permit either. Much like in the UK. One alternativ is to make your own nitric acid by destillation using one part calcium nitrate Ca (NO3)2, and two parts sodium hydrogen sulfate NaHSO4.
As one of the best nitric acid suppliers, it supplies only the best quality to its clients. Nitric acid is a highly corrosive mineral acid that is colorless. Older samples of nitric acid tend to have a yellow cast due to decomposition into oxides of nitrogen and water. Commercial nitric acids tend to consist of 68% water. Chemical Uses
When working with silver, we usually dilute our concentrated nitric acid with an equal volume of water, so the 38% will work well right out of the bottle. When using it to make aqua regia, we usually use it in its concentrated form, but the 38% will still work fine, just adding a little more water to the AR.
Gold processing - Refining, Smelting, Purifying: Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in …
Standard 67-70% Nitric is usually used in 2 ways: (1) full strength when making up aqua regia with HCl and (2) diluted 50/50 with distilled water to dissolve silver (or, certain base metals). (1) For aqua regia, the 50% could be used with little sace in speed. (2) For the equivalent of 50/50, 70% nitric, use the 50% acid and add 27%, by ...
JSP! NITRIC ACID SUBSTITUTE (sodium nitrate) 16ozs [gt530] - Nitric acid substitute to be mixed with hydrochloric acid. This is used to dissolve gold for later precipitation. Instructions using JSP® NITRIC ACID SUBSTITUTE a) Dissolve 80 grams (2.8 oz) of JSP® Nitric Acid Substitute.
3: Roughly 4ml of nitric is needed for every gram of base metals, equals roughly 800ml of nitric for 200gr of pins. With nitric acid @ 50 dollars per 500 ml you will loose money: 2 bottles of 500 ml HNO3, 100 dollars at least for 0,5 grams max. of gold which eqauls about 25 dollar.
That MX3 has all the same advantages (as sodium nitrate) OVER NITRIC ACID. Such as MX3 also being more economical than nitric acid. That much is true. Their own prices are $9.90/pound for sodium nitrate but $15.99/pound for MX3. So whatever MX3 is, it is NOT more economical than sodium nitrate. That being said, their sodium nitrate …
I already have 2L of concentrated nitric to use For aqua regia. But looking for a cheaper alternative for dissolving base metals, from gold filled scrap. I've seen Geo videos on the poor man's nitric, using sulfuric acid and nitrate salts in e-scrap. But didn't know if it was a viable source of acid for good filled scrap.

Producing Aqua Regia. The first step to refining gold involves creating aqua regia – a mix of nitric acid and hydrochloric acid named for its ability to melt gold – and applying it to the gold in question. After choosing a …
Yesterday at 10:20 AM. #1. Hello I'm trying to use sodium nitrate + sulfuric acid to make 70% nitric acid. I understand the formula is a 2-1 mole = 1-2 mole nitric. But I can not get this to turn out right. If I add 1700 grams of sodium nitrate and 850 grams of sulfuric acid and 550 grams of water this should give me almost 2 liters of nitric ...
Ochsenkühn-Petropulu et al. showed that 29–96% of REEs in bauxite residue could be extracted by direct leaching using 0.5 M nitric acid, at the liquid to solid ratio of 50, the retention time of 24h, and at room temperature. Under this condition, a scandium extraction of 83.8% was obtained, with co-extracted iron of 2.2%.
Oct 13, 2008. #9. Nitric acid can indeed be easily made out of concentrated sulfuric acid and a nitrate. Simply mix the finely groud powder and the acid intimately in a large shallow glas jar. Make a layer of no more then 1 cm thick. In the center of the jar you need to place an empty glass cup.
If you're looking for a $0.99 answer & a 5 minute solution, you're out of luck. These chemicals, even "" ones, can kill & maim in the hands of a moron. Or someone with no experience & no patience. No offense :shock:

A third drawback is that AP does not work effectively on all base metal substrates. 1) Easy chemical access. 2) Reuseable. 3) Low fumes (no nitric oxides). 4) Cheap. 5) Easy to use. 6) Works on a variety of copper and base metal substrates. 8) Work is done via the CuCl2 molecule.
Another alternative is to add Calcium Hydroxide to the Ammonium Nitrate. This gives off Ammonia Gas which can be used to precipitate PGMs from a Chloride salt solution. The Ammonia reacts with the excess HCL in the solution producing Ammonium Chloride and also reacts with any Nitric Acid to produce Ammonium Nitrate.
Also worth asking whether you want the Nitric acid to dissolve away base metals, or only to refine the gold at the end. If you are wanting to dissolve away a lot of base metals, then you really need reasonably concentrated Nitric acid, if you are just wanting to refine some foils, the PMAR or even bleach will do the job. D.
Dump the ground sodium nitrate into a large jar (gallon size pickle jar). Then add another 1/2 cup of water to the blender container and rinse the residue into the 1 gallon jar. Stir the sodium nitrate and water mix and let that sit for at least 1 hour. Now add 1 quart of sulfuric acid (auto battery acid).
1 lb bag. $15.99. MX3-10. 10 lb bag. $129.99. A superior, dry, non-hazardous substitute for nitric acid when making aqua regia. This very dense chemical mixture dissolves instantly, making it far more economical to use than sodium nitrate. MX3 possesses all of the advantages that sodium nitrate has.
Yes - & I should have noted that "if his nitric is dissolving gold" then it is not only nitric Somewhere in his process a chloride is being introduces to his nitric resulting in the creation of AR (Aqua Regia) even if it is a weak AR that is being created In other words - when he is using his nitric to dissolve the silver/copper/base metals - …

To a gallon of tap water, add 3 lbs of rock salt, stir occasionally and let it dissolve. Decant the brine water, or filter through a coffee filter of there is trash in the rock salt. The ideal gold leaching formula is 7:1 (7 parts brine water to 1 part nitric acid), at a leaching temperature between, a low of 70 F and a maximum of 176 F.
I live in Wisconsin too and got my nitric off of ebay. I paid $55 total for 500ml of it. The same seller has a 1L jug for $69, which I should have gotten but really didn't need that much yet so i saved myself $14, even tho it would have been most cost effective to buy the bigger one. Oh well.
As I recall, if you make purchases from a chemical supply house, and buy reagent grades of acids, they are concentrated. Be prepared to pay a heavy price for them. They are far more expensive than commercial grades of acids, which are more than adequate for refining. You may come to understand that nitric acid is difficult to buy.
