What Colour are bromide ions?
Halide ions undergo a series of unique reactions that allow an unknown solid or aqueous sample to be tested for the presence of chloride, bromide or iodide ions….(4) Reactions of halide ions:
|Halide ion||Observation with Pb(NO3)2(aq)|
|Iodide||bright yellow precipitate|
What is the colour of silver iodide?
Silver iodide is an inorganic compound with the formula AgI. The compound is a bright yellow solid, but samples almost always contain impurities of metallic silver that give a gray coloration.
Why is ammonia added to silver halides?
The ammonia combines with silver ions to produce a complex ion called the diamminesilver(I) ion, [Ag(NH3)2]+. A solution in contact with one of the silver halide precipitates will contain a very small concentration of dissolved silver ions. The effect of adding the ammonia is to lower this concentration still further.
What is the Colour of fluorine?
SUMMARY Moissan’s observation, that fluorine gas is yellow, has been confirmed. At an early stage in their studies, all chemistry students are taught that fluorine is yellow or greenish-yellow in colour [1,2] .

What is the chemical name for Br?
Bromine (Br), chemical element, a deep red noxious liquid, and a member of the halogen elements, or Group 17 (Group VIIa) of the periodic table.
Are there any precipitates that have the same colour?
All carboates of s block group 2 elements are precipitates. Sulfates of Ba 2+ and Sr 2+ are precipitates. Hydroxide of Mg 2+ is a precipitate. Can colours of precipitates be used everytime to identify compounds? Cannot. Some precipitates have same colour. As an example, both SrSO 4 and BaSO 4 are white precipitates.
What is the colour of solution in halogens?
The colour in solution is red, a kind of attractive dark wine red. As it is equilibrium, the solution behaves as an iodine reservoir, which can be formed as it is used up until there is no triiodide left. Rep: ? You get these gems as you gain rep from other members for making good contributions and giving helpful advice.
Which is a colourless precipitate of lead + 2 ion?
Ferrous chloride (FeCl 2) – colourless or green Lets consider lead +2 ion. PbI 2 is yellow colour precipitate and PbCl 2 is white precipitate. So when anion vary, color of preciptate also vary. Does nitrate ion form precipitates with cations?
What is the colour of anion Accoring to a precipitate?
Accoring to the anion or cation, colour can be vary. Chloride ion (anion) is common for both compounds. But their colours are different. Lets consider lead +2 ion. PbI 2 is yellow colour precipitate and PbCl 2 is white precipitate. So when anion vary, color of preciptate also vary. Does nitrate ion form precipitates with cations?
