It is a test for presence of phenol. Fe itself is a transition metal that form a complex ions with phenol. Hence, the Fe can undergo d-d transition that give a colour which is purple in this case.

How neutral fecl3 solution prepare?
Take 1 ml FeCl3 solution. add ammonia solution drop wise till brown precipitate just form. Now again add FeCl3 solution till brown precipitate just dissolve. This is your Neutral FeCl3 solution.
What is the concentration of FeCl3 in a solution prepared by dissolving 40.0 g of FeCl3 in enough water to make 275 mL of solution?
Look up or calculate the molecular weight/molar mass of FeCl3. Then... 40.0 g FeCl3/MW FeCl3/0.275 L = M (concentration of FeCl3 in solution)
What is the nomenclature for FeCl3?
FeCl3 has the name iron III chloride
What is an ionic equation for FeCl3 plus H2SO4?
FeCl3 + H2O4-2 +Zn
Salicyclic acid gives a positive test with FeCl3?
why does salicylic acid give a positive test with FeCl3
What happen the color if FeCl3 and KCNS and distilled water mixed?
the KCNS is tranparent when you mixed with the FeCl3 is like a violet

Is phenol easier or more difficult to substitute with bromine than benzene?
The substitution reactions of phenol are easier than benzene, phenol directly reacts with bromine and gives tribromo phenol while benzene requires FeCl3 as a catalyst and gives mono bromo phenol.
What are identification tests of phenol?
You add a specific ionic compound in a solution to determine if phenol or any of its derivatives are present. Ferric chloride (FeCl3) for example, can be used for such tests. Basically, when you mix the solution with the compound, the ions will interact with the phenol molecules or groups, and as a result, the solution will briefly change color. If there is no colour change in the solution, this suggest there is no phenol or phenol-based molecules in your solution.
What is the product of eugenol and FeCl3?
he balanced equation for the reaction involved is as follows: C10H12O2 + Br2 + H2O ---> C10H13O3Br + HBr. Some C10H12O2Br2 will form as well. Some C10H12O2Br2 will form as well. Is eugenol …
