The chromyl chloride test need heating a sample containing chloride with potassium dichromate and concentrated sulfuric acid.
If chloride is present, chromyl chloride is formed and red fumes of CrO2Cl2 are released If there is no chloride present, no red fumes are produced. Chromyl Chloride not formed with fluorides, bromides, iodides and cyanides, it is only test specific for chlorides
Chromyl chloride test is given by only chloride salts which are infer whether there is halide predominantly ionic while covalent chlorides such as HgCl2 do not generate Cl- ions thus won't give this test.
