Hello, Anyone willing to sell a few pounds of Sodium Nitrate ? I want to try to make nitric with, it's supposed to make greater concentration Nitric acid. Sodium Nitrate is more than twice as soluble as Potassium nitrate at 30°C. Or anyone has a good source in Canada ? I'll pay for the NaNO3 + shippping to me. Thanks a lot.

But last time when dissolving gold bond wires recovered from IC chips i found the process taking forever. So i wanted to try Poor mans AR for a change. Now, i first added 60 ml of 30% HCL and sodium nitrate to a few grams of foils and they where quickly dissolved leaving a nice yellow solution.

One way to get pure sodium nitrate would be to add silver nitrate to the solution, silver ions react with the chloride and precipitate out as silver chloride, leaving sodium nitrate in solution. By being careful with how much silver nitrate is added, a re-crystallization of the solution could remove most of the contaminants in a following step.

Sodium nitrite is much more common in curing meat than sodium nitrate. An easy test is adding your powder to silver nitrate solution, if it is nitrate, there will be no precipitation, if it is nitrite, there will be. Or, make a dilute solution (2M) of sulfuric acid and chill it. Then add your ''sodium nitrate'' to it.

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).

In the end you will have decently pure, (99.7% or so), and separate gold and silver to re-alloy to 18k for your use. All without any need to make or buy nitric acid. If you need the gold more pure than that you can simply re-dissolve it and drop it again. With good attention to washing you can get to .9997.

The Inquartation method is one of the most common methods of refining low and medium karat gold jewelry (9K-18K) and can also serve the first step in refining sterling silver. Inquarting usually doesn't apply to high karat gold jewelry (21K-24K) since it is low in silver content. A low silver content (less then 8%) will not create passivation of the metal and …

If you want to leach gold you need an oxidizing environment (add chlorine gas or clorox) until you reach an ORP of 1000mV, at a Ph of about 5, hopefully warm temperature and you will leach gold. Once in solution, separate liquid from solids, reduce the ORP to 100 -500 mV using NaHSO3 and your gold will precipitate.

Benton, Arkansas. Jul 25, 2016. #2. Melting gold foils never gains nothing and it is foolish. You'll never be able to purify the gold in the melt. Forget that! The only way is to use AR on the foils and then drop the gold with either SMB or other precipitant. It's easier to dissolve the foils, as is, than it is to dissolve them after melting.

Sodium nitrate is used as an ingredient in fertilizers, explosives, and in solid rocket propellants, as well as in glass and pottery enamels; the compound has been mined extensively for those purposes. Sodium nitrate is commonly used in gold refining for making aqua regia which is used for recovery of gold, platinum and other precious metals.

So by my estimations 300gm per 100mm of distilled water. If you feel like converting it to the more desirable NaNO3 (due to higher molar solubility: Na=10.7M whereas Mg=9.6M =moles of available nitrate per liter @25C; also Na salt is less hygroscopic) you can do so via: Na2CO3 + Mg (NO3)2 --> MgCO3 + 2NaNO3.

Moderator. 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 this should give me 21 moles of nitric + 30% water.
