Can perform chromyl chloride test in the presence of other halides?
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.
