Can you extract anything from it?If you can, please specify the specific method of extraction.I have a large amount of thanks.
(3) dilute the above solution by 3-5 times, place the iron or copper pieces into the solution, and the silver will soon be replaced. (stirring the solution often).2Ag+ (2e) 2Ag degrees (silver)Cu DEG (2e) Cu2+ (copper)(4) if the copper block is no longer reactive (i.e., the silver is no longer precipitated), pour the solution into another beaker. The bottom of the cup is sponge like silver, then filtered, and then rinsed with a sponge like silver to neutral (PH test paper)
They will die out between the collected, dissolved in nitric acid and silver nitrate away debris, heating (not smoking).(2) filter the solution to remove dust, sawdust, etc. the filter paper is rinsed several times with deionized water.
(5) the clean sponge like silver and filter into the pot with a musket burning silver block.(6) recovery of silver from silver deep fried liquid (chemical polishing liquid);The main component of the polishing liquid is potassium cyanide hydrogen peroxide, so the main cyanide (silver) can be precipitated. Pour the polishing liquid into the cup, add nitric acid to the pH value of about 5, and then boil on the electric stove for 1-2 minutes (silver) to precipitate.Rinse the precipitate silver until it is neutral and then burn into a silver mass.
