silver chloride?
silver oxide?
silver metal?
Actually only silver chloride is a salt of the three substances above.
Silver oxide have covalent bindings and silver metal have metallic bonds.
To be called a salt it has to have ionic bonds, like silver nitrate or silver cyanide.

Joking aside, before anyone suggests any treatment with acids, remember that silver cyanide is a white silver salt that is used for plating (according to wikipedia) and mixing it with acids could easily kill an unsuspecting person.

sakosakarian, you asked about cyanide solutions in another thread. Is this a silver salt used for plating? Does it contain cyanide? Is there any markings on the silver crystal salt?

i have silver chloride and i want i want to make silver as a metal not dust.
That helps. There are several ways to convert silver chloride back to metallic silver. You'll have to decide which method best suits your circumstances.

Try a search for the words "silver chloride convert" (without the quotes). You'll find information on several different methods.

Silver nitrate? You must be more specific. Provide more information if you hope to receive viable replies.

Silver chloride? It should be a white powder substance. If you want to make it metallic silver you should reduce it. The best way in my opinion is to reduce it first chemically by adding some piece of scrap iron to it (nuts, bolts, nails, whatever), then add some dilute sulfuric acid (some fresh car battery acid will work). This will convert the silver chloride into metallic silver (dust) while the iron gets converted to ferrous sulfide and chloride(solution). Remove the iron pieces, wash off the gray silver powder, collect your gray powder together, rinse well, filter the dust and melt it to get it back to a solid shiny silver metal. Hope this helps.
 
thanks a lot santiago. theres a test after applying aqua regia to know if theres any gold left in the solution called stannous chloride but i cant find it in Lebanon. is there any other u know of?
 
Make your stannous chloride (tin dissolved in HCl acid).
They should have tin in Lebanon.
(Or lead free solder 95% tin).

Study Hokes and the forum to learn how to make and use the stannous chloride, to learn how to prepare the gold in aqua regia solution before the test will work(removing free nitric acid from solution), and to learn what the different colors the stannous chloride solution gives in tests with different metals dissolved in solution.
 
Hi,
It is explained in the "guided tour", and many other things !!
You need Tin ( Sn )

General reaction list, nr 10 :

" SnCl2= Stannous Chloride= Used to test solutions for precious metals. Made by dissolving metallic tin in hot muriatic acid. Loses strength when stored. Made by adding 1-2 grams of powdered tin to 30 mL of HCl. Heat until fizzing starts. A little extra undissolved tin powder helps the solution keep for longer. Keep air out of container when stored to extend life.
Positive color test as follows:
Purple/Black color is Gold in solution, the darker the spot the more Gold.
Yellow/Brown that turns to Blue-Green after 30 seconds indicates Palladium in solution, the darker the spot the more Palladium.
Orange/Brown color is Platinum in solution, the darker the spot the more Platinum."

Yes, sakosakarian... but not as sensitive as stannous chloride. If you got rid of your nitric acid already you should dilute your solution to about a half liter or so, Hold your solution up in the light then add a fresh (green) crystal of ferrous sulfate. If gold is present you should see a brown or black cloud form immediately around the ferrous sulfate crystal. If you also can't get ferrous sulfate, just make some by taking about a few hundred grams or so of scrap metal. Finishing nails work well also. Put them in a bucket (OUTSIDE) and cover them with some battery solution (the type the sell to refill car batteries). Wait until there's no more reaction and when you look in the bucket you should see some greyish-green colored crystals mixed with the remaining iron that didn't dissolve. Remove the scrap iron then wash the crsytals with cold water but try not to add too much water to make them dissolve. These are IMPURE ferrous sulfate crystals which you can also use for testing gold. Again, their not as sensitive as stannous chloride but it works, and if gold is present, you can just dissolve those crystals in water, acidify the solution with a little muriatic acid (HCl) until it turns green, then add it slowly to get out the remaining gold.
