Sodium nitrate is a white solid very soluble in water.
Single salt solubilities were regressed in Aspen within weight percent of literature values. These were combined into a single Aspen model and used in the mixed salt studies. A simulated nitric acid waste containing mixed aluminum, calcium, iron, magnesium and sodium nitrate was tested to determine points of solubility between 25 and 100 C.
Making Poorman Aqua Regia and Dissolving Metals in It.: Hydrochloric acid 10 Moles per L or 31 percent with any Nitrate salt (Magnesium Nitrate, Calcium Nitrate, Sodium Nitrate, etc expect ammonia nitrate due to the ammonia base) you can make weak Aqua is an alternative to using .
native gold from goldbearing ores or the dissolution of gold metal during the recycling of electronic and precious metal scrap is performed every day using hazardous chemicals such as sodium cyanide or aqua regia. These chemicals represent health and safety risks for workers and a serious threat for the environment. However, even if several
Sodium nitrate is a colorless, odorless, crystalline compound, sometimes referred to as soda niter, nitrate of soda or Chile saltpeter. It is used for making potassium nitrate, fertilizers, explosives, in the production of highstrength glass, some limited pharmaceuticals and to preserve meats.
The three enduse products, two containing 65% sodium nitrate and one with % sodium nitrate, are all used as fumigant gas cartridges designed to be placed in burrows.

Tzanetakis and Scott also used hydrochloric acid to dissolve batteries, and D2EHPA in kerosene was used to recover rare earths followed by electrochemical recovery of a nickel–cobalt alloy [4, 5]. Fernandes et al. developed a process involving concentrated chloride solutions for nickel metal hydride battery recycling, using the extrac
13. Melt your dried gold (now a powder) If using a torch, first wrap the powder in tissue paper and then soak that in alcohol. We also recommend using a Burno crucible, to keep your gold from being blown away by the gas pressure of the torch. The gold will again take on the appearance of metal.
Jul 29, 2010· Silver nitrate, The video was kinda neat and the music was good. However, you seemed to have skipped over the most important part actually dropping the gold. The topic of the thread is using sodium nitrite to drop gold. Is that what you used?
2 days ago· With the crystallization of sodium nitrate, mother liquor composition moves from point B to point E, at which NaNO 3 and KNO 3 reach cosaturation. If the evaporation continues, it enters the cocrystallized zone of sodium nitrate and potassium nitrate, and here, potassium nitrate will also being to precipitate.
I wonder if making crude Nitric acid with 31 percent Hydrochloric acid and Sodium Nitrate to dissolve more gold would work? It would be quite expensive 60 dollars for 100 g Sodium Nitrate on Ebay. Also, HCl + H202 did dissolve gold I plated with it! You can clearly see the gold.
The heap leaching of copper bearing ores is improved by using sodium nitrate as an oxidizing chemical reactive in a sulphuric acid leaching solution. In particular, the ore is crushed to <6 mm and stored in heaps less than twelve meters high. The heaps are irrigated with a dilute solution consisting essentially of sulphuric acid and sodium nitrate to produce a leach product.
