It can be made by reacting a soluble silver salt with a soluble chloride salt. As long as you are doing everything under controlled conditions (same amounts of everything, same temperature and so on), the time taken gives a good guide to the reactivity of the halogenoalkanes - the quicker the precipitate appears, the more reactive the halogenoalkane. For example: The order of reactivity reflects the strengths of the carbon-halogen bonds. Adding concentrated sulfuric acid to a solid sample of one of the halides gives the following results: The only possible confusion is between a fluoride and a chloridethey behave identically under these conditions. Sodium nitrate is also soluble in water so after the reaction has occured, sodium and nitrate ions are still floating in solution. WebAqueous solutions of potassium bromide and silver nitrate react to form a white precipitate. In a chemical compound, silver ions tend to have a one plus charge, so we can write This occurs with silver chloride, and with silver bromide if the ammonia is concentrated.
