You can still buy calcium nitrate, it's relatively easily to make the calcium nitrate into sodium nitrate by adding baking soda to a calcium nitrate solution. Just add baking soda in portions until no more insoluble calcium carbonate is formed on further addition.

Pacific NW. Apr 6, 2018. #16. Using sodium nitrite as a precipitant for gold. Sodium nitrite and hydrochloric acid = nitrous acid and sodium chloride (table salt) HCl + NaNO2 --> HNO2 + NaCl. Gold chloride reduced with sodium nitrite = elemental gold sodium chloride (salt) and nitrogen dioxide gas. AuCl3 + 3NaNO2 --> Au + 3NaCl + NO2.

Mar 27, 2012. #1. I was making an electrolyte as instructed in lazersteve's videos to refine my sterling silver and I ran out of nitric acid before completely dissolving the 100g of silver needed for the electrolyte. It is about 30g off and while it is forming crystals on the negative plate, it isn't enough to make it worth the effort.

This ancient Gold Refining method is one in that the nitre must be " projected " upon the gold just before it melts, as it has little effect on molten gold. The method is …

I would then look for a fertilizer called nitrate of soda (sodium nitrate, NaNO3). Then I would try to find sulfuric acid (battery acid [low concentration of H2SO4] or drain cleaner thats in a bottle, inside its own bag. [its 98% sulfuric]) to make my own, with lazersteves cold method.

Sodium nitrate doesn't even make powerful bombs since the sodium ion has a relatively strong bond to the nitrate ion compared to the other alkali metals. If you …

Hi, I am having a major problem Lazer steves Nitric acid procedure. Here is how i do it,.its for a 5x batch of lazer steves recipe Bring 500 ml of dstilled water to a boil I start adding 25ml of sodium nitrate at a time until all 800grams of sodium nitrate is boiling in solution . It looks like it is all mixed in solution and i even boil for a additional 10 …

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).

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.

Jul 30, 2010. #1. OK this is my story I made aqua regia using the sodium nitrate/meuratic acid method and proceeded to dissolve about a pound of gold plated pins fingers and chips while capturing the fumes in several 1 gallon glass jars and reacting that with water to reclaim the valuable nitric acid. After the metal was dissolved I filtered ...

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.

I heated and dried out the filters and I will run through nitric acid (½ pound sodium nitrate, and 32 ounces sulfuric acid) and take out all the copper leaving the gold hopefully. Than run the gold through Aqua Rega (½ pound of sodium nitrate, and 32 ounces HCL). I'm hoping this will work. Pins are somewhat moor different than CPUs and …

There are various types of gold smelting flux available on the market. Beyond just gold smelting, flux is also used in other areas of metallurgy and metal joining. Below are some …

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.

Feb 25, 2009. #5. So, to answer Arthurs original question, using 1.205 liters of 70 percent nitric to disolve one pound of copper, and one liter of 70 containing 994 grams of nitic, and that being equal to 1342 grams of sodium nitrate, we would need 1.205 times 1342. Or, 1617 grams of sodium nitrate to dislve 1 pound of copper.

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.

Does anyone know a supplier for a decent amount of sodium nitrite ( not sodium nitrate). that's 99 percent ire or better. In Europe/UK this isn't expensive but so far from what i've seen in the US it's very expensive Duda no longer sells it. thanks. GOG

What the Ishor website actually claims is: 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 …

Mar 4, 2023. #3. Yggdrasil said: Nitric should not need improving. And adding soemthing to it will certainly not improve anything. If it has been stored in a dark place or a brown bottle it should be ok. It was kept in the brown bottle in the foam shipping pad. It is, however, beyond the 2 year expected lifespan.
