By using sulphur- a drop of heated liquid sulphur should be applied to the metal, which will create a dark patch of silver sulphide if the metal is pure silver (this is easily wiped off again).
It is also possible to do this test by applying the combined flames from two lighted matches to the metal, but in this case the sulphide mark will NOT be removable.

How do you test for presence of iodide ion?
You can test for the presence of iodide ions using silver nitrate. When silver nitrate is added to a solution containing iodide ions, a yellow precipitate of silver iodide forms. This precipitate confirms the presence of iodide ions in the solution.
What is the difference between fehling's solution and tollens reagent?
Fehling's solution is used to test for the presence of reducing sugars, while Tollens reagent is used to test for the presence of aldehydes. Fehling's solution contains cupric ions, while Tollens reagent contains silver ions. When a reducing sugar reacts with Fehling's solution, a brick-red precipitate forms, while with Tollens reagent, silver ions are reduced to form a silver mirror on the test tube.
What is mohr's salt test?
Mohr's salt test is a chemical test used to detect the presence of chloride ions in a solution. It involves adding a silver nitrate solution to the sample, which forms a white precipitate of silver chloride if chloride ions are present. The formation of the precipitate confirms the presence of chloride ions in the solution.
Why does silver nitrate test provide negative result on the presence of a chloride ion?
The silver nitrate test provides a negative result on the presence of a chloride ion because silver chloride is insoluble in water and forms a white precipitate when silver ions react with chloride ions. This precipitate masks the presence of the chloride ion in the test solution, giving a negative result.
How do you test for chloride ions?
Look in your solubility table. Look at Cl-, almost everything is soluted well, except: Hg+ or Ag+ Which is mercury and silver. I suggest you use silvernitrate (AgNO3) And then check by adding ammonia solution to dissolve the ppt.
How do you test for bromide ions?
One common test for bromide ions is the silver nitrate test, where adding silver nitrate to a solution containing bromide ions produces a cream-colored precipitate of silver bromide. Another test is the starch-iodide test, which involves adding starch and iodine solution to the sample, causing a blue color to form in the presence of bromide ions.

What is the test reagent for chloride ion?
Silver nitrate (AgNO3) is commonly used as the test reagent for chloride ions. When silver nitrate is added to a solution containing chloride ions, a white precipitate of silver chloride (AgCl) forms. This reaction is often used to detect the presence of chloride ions in a solution.

How can you test a solution for the presence of ba ions?
Add a sulfate solution: BaSO4 precipitates!
Add a drop of silver nitrate to both a distilled water test tube and to the test tube containing the salt solution in the test tube. What do you observe?
Should be a white precipitate. Indicative of the presence of either Na or Mg. Wrong again people. Silver Nitrate is used to test for the presence of chloride ions. Such as those in your salt a.k.a sodium chloride and yes adding silver nitrate to your salt solution will create a white precipitate.
What happens when silver nitrate reacts with carbonate solution?
When silver nitrate, a soluble solution, is mixed with a carbonate solution a precipitation reaction (double replacement reaction) takes place forming nitrate ions and the insoluble solid silver carbonate.
Silver nitrate is used for testing of which chemicals?
Silver nitrate is commonly used to test for the presence of halide ions, such as chloride, bromide, and iodide ions. When silver nitrate is added to a solution containing these ions, characteristic precipitates are formed: white for chloride ions, cream for bromide ions, and yellow for iodide ions.
What compound forms precipitates in limit test of chloride?
Silver chloride (AgCl) forms a white precipitate in the limit test of chloride ions when reacted with silver nitrate (AgNO3). This precipitation reaction is commonly used to detect the presence of chloride ions in a solution.
