WebColored speckles for use in granular detergentsColored speckles for use in granular detergents All the precipitates change color if they are exposed to light, taking on gray or purple tints. It reflects the change in the way that the halide ion is produced as you go from primary to secondary to tertiary halogenoalkanes. 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.
