actually,chromyl chloride test is meant to infer whether there is hallide present in the salt.if the test proves to be +ve,then hallide ion is present in the given salt.
However let us remember that predominantly covalent chlorides such as HgCl2 and alkyl chlorides,wont give chromyl chloride test.This could be used to good purpose. Since detection of chloride by silver nitrate,followed by its dissolution in dilute ammonia and a negative chromyl chloride test would indicate that the given chloride is covalent and not ionic.
What else can I help you with?
How dou you show the presence of both iodide and sulfate in a mixture?
You can show the presence of Sulphate in a mixture by adding barium chloride solution followed by dil HCl. A white precipitate that does not dissolvev in dil HCl indicates the presence of sulphate ioins. Ba2+ (aq) + SO4^2- (aq) ---------> BaSO4 (s) Iodide ions can be shown by adding to the suspected iodide a solution of lead nitrate where upon a brilliant yellow ppt is thrown down Pb2+ (aq) + 2 I- (aq) --------> PbI2 (aq) Also addition of silver nitrate will give a yellow ppt which is insoluble in ammonia solution. Ag+ (aq) + I- (aq) ----------> AgI (s)
How you might test a sample of an unknown white solid to determine if it was table salt sodium chloride?
One way to test for table salt (sodium chloride) is to conduct a flame test. When the sample is heated in a Bunsen burner flame, table salt imparts a yellow color to the flame. Another test is to perform a solubility test by dissolving the sample in water; table salt is highly soluble in water, producing a clear solution. Finally, you can test for the presence of chloride ions using silver nitrate solution, which forms a white precipitate of silver chloride.
How could you detect the presence of the chloride ion?
It Is determined in the flame test. A flame test is when u take the solution and put it on an object non flammable and hold it into the fire and the color of the fire will change. The test is constructed so that depending on the ions in the solution the flame with show whether It has a specific ion based on its distinctive Color.
How can you determine if the decomposition of potassium chlorate is complete?
You can determine if the decomposition of potassium chlorate is complete by observing if there are no more oxygen gas bubbles being evolved. Additionally, you can perform a residue test to check for the presence of any solid potassium chloride left behind in the reaction vessel. It is also important to ensure that the reaction mixture has been heated for a sufficient amount of time to allow for complete decomposition.
Suggest a test chemical that can be added to waste water to precipitate lead II ions show a chemical equation for the formation of the precipitate?
Put a little hydrochloric acid in the water sample. 2HCl + Pb -> H2 + PbCl2. Lead chloride is insoluble and its density is much higher than that of water. You can then perform a test on the precipitate to determine the ratio of lead chloride to silver chloride in your precipitate.
How do you test for the presence of chlorine in aluminium chloride?
The sample of aluminum chloride be treated with some ammonia(1:1)aqueous solution and filtered.To the filterate add a few drops of 2N HNO3, aqueous solution, followed by a few drops of 1% aqueous solution of silver nitrate. Appearance of curdy white precipitate soluble in dilute ammonia aqueous solution would indicate presence of chloride. Since aluminum chloride is quite covalent, the chromyl chloride test may not be very effective
How do you go from a chloride to nh2 group?
To convert a chloride to an amino group (NH2), you can perform a nucleophilic substitution reaction. One common method is to react the chloride with ammonia or an amine in the presence of a base. This substitution reaction replaces the chloride with the amino group, resulting in the desired product.
How can you detect the presence of tannic acid in tea by experiment?
To detect the presence of tannic acid in tea, you can perform a simple experiment by adding a few drops of ferric chloride solution to the tea. If tannic acid is present, a blue-black color will form due to the formation of a complex between the tannic acid and ferric chloride. This color change indicates the presence of tannic acid in the tea.
How could you detect the presence of the Ag ion?
Silver ions could be detected with the use of a silver ion selective electrode, mass spectrometry, or using certain chemical reactions (ie precipitation when a source of chloride ions is added, complexation using ammonia, etc).
How dou you show the presence of both iodide and sulfate in a mixture?

Why do the sublimation of ammonium chloride in the fume hood?
This question is not grammatically correct. Why does one perform the sublimation of ammonium chloride in a fumehood? Because it creates ammonia and hydrogen chloride vapors, both of which are caustic.
What is the Cisco Unified Presence?
The intent of Cisco Unified Presence is to enable its users to perform on their job more efficiently. Increasing efficiency decreases the amount of time required to perform same task.
What is aerobic bacterium?
Bacteria that can perform metabolic functions in the presence of air.
Why is a plant cell able to perform photosynthesis?
Due to the presence of chloroplasts in it.
Where does Hamlet want the actors to perform?
At court; somewhere in Elsinore in the presence of the King.
How do you do drilling mud salinity test?
Run a retort to determine the ratio of water in the mud, perform chloride titrations
How could you tell the difference between an iron chloride and sodium chloride solution?
One way to differentiate between iron chloride and sodium chloride solutions is to perform a chemical test using silver nitrate. Iron chloride solution will form a white precipitate of silver chloride, while sodium chloride solution will not react with silver nitrate. Another method is to use a flame test: iron chloride imparts a yellow color to the flame, while sodium chloride does not.
