Various precipitates may be formed from the reaction between the silver and Silver fluoride is soluble, so no precipitate is formed. Sodium chloride For a primary halogenoalkane, the main reaction is one between the halogenoalkane and water in the solvent. They can be distinguished by dissolving the original solid in water and then testing with silver nitrate solution. Silver nitrate solution is then added, and the halide can be identified from the following products: The chloride, bromide and iodide precipitates are shown in the photograph: The chloride precipitate is easily identified, but the other two are quite similar to each other. The colour of copper sulphate solution fades due to the formation of light green solution of iron sulphate.
