Sodium nitrate and HCl issue
Hi there, Been trying to make some nitric acid with sodium nitrate. But there is the problem, whenever I add HCl to sodium nitrate it bubbles and s out of the beaker. I'm suspecting my so called sodium nitrate is something else. Can anyone guide me on it? Also is there a way to extract nitric acid from sodium nitrate and hcl mix? Thank you
AgNO3 + NaCl = AgCl + NaNO3 | Silver Nitrate + Sodium …
AgNO 3 + NaCl = AgCl + NaNO 3 | Silver Nitrate + Sodium Chloride Reaction. When aqueous AgNO 3 and aqueous NaCl compounds are mixed together, there is a high chance of giving a white colour precipitate if initial silver nitrate and initial sodium chloride concentrations are considerably high. . That means, AgNO 3 and NaCl is a precipitation reac

Ammonium nitrate and silver
Silver nitrate and ammonia is not suggested for the reason you were asking. If you are dissolving your ammonium nitrate then you not only have your nitrate in solution but also your ammonia. For that reason I would think it should be avoided unless you first remove the ammonia from your nitric before adding silver.
Making Sodium Nitrate ? | Page 2 | Gold Refining & Metal Extraction …
What really sounded interesting was the cheap powdered drain cleaner. I would have expected the lye but never thought there might be sodium nitrate which should work for DIY nitric or AR without needing to make ammonium nitrate. The sodium hydroxide would be worth saving too. That is assuming it is as easy to separate the 3 ingredients as the ...
Solved For Expt. #1
Question: For Expt. #1 - silver (I) nitrate and sodium carbonate, if a reaction occurred here, what is the integer coefficient of the reactant cation? Make sure your answer is an integer. Enter the value and nothing else. If there is no NIE, then write no NIE and nothing else. For Expt. #2 - sodium chloride and potassium nitrate, if a ...
Nitrate of Soda V Ammonium Sulfate
Ammonium Nitrate is fine if you are going to distill the nitirc acid off, but using my 'cold' method it's not a good choice. The main reason is because the resulting ammonium sulfate (70.6 g/100 mL (0 °C) solubility ) salt has a much higher water solubility than the resulting sodium sulfate salt (4.76 g/100 ml (0 °C) solubility).

PPT silver from Silver Nitrate
I've been reading some older books on silver- One mentions that Ag can be PPT from Silver Nitrate with Hydrogen gas if the Silver Nitrate is heated some... Forums. New posts ... That is very ill advised to let that evaporate, especially if any sodium or potassium salts are present. if, however, I add say, hydrazine to it. I don't get silver ...
Reducing Silver nitrate to metallic silver | Page 2 | Gold …
The silver sent out to assay was melted and shotted. All of the feedstock for the refining process is sterling and we assay it with the Volhard titration as well. I prefer the sodium formate reduction of silver to a silver cell because we inquart karat into the starting alloy and produce a high purity gold residue as a side benefit.
