Haloalkane test. Image 4 of 7. Precipitates in test tubes. Haloalkanes are formed when a halogen is substituted into an alkane. Silver nitrate has been added to three test tubes containing a haloalkane and sodium hydroxide. The silver nitrate reacts with the halogen to produce a precipitate. The colour of the precipitate depends on the halogen ion present. The halogen ion in these test tubes from left to right are, chlorine (white), bromine (pale cream) and iodine (pale yellow). For a sequence showing the test see images A500/437 to A500/543.
