The ferric chloride test is used to determine the presence or absence of phenols in a given sample. Enols give positive results as well. The bromine test is useful to confirm the result, although modern spectroscopic techniques (e.g. NMR and IR spectroscopy) are far superior in determining the identity of the unknown. The quantity of total phenols may be spectroscopically determined by the Folin-Ciocalteau assay.
I think neutral ferric chloride is prepared by mixing iron(III) chloride with ammonium hydroxide.
Normal solution of ferric chloride is acidic in nature and phenol is also acidic so neutral ferric chloride is more useful.
You most likely mean Fe3+. This is not a compound, it is a monotaomic ion of the element iron.Because it carries a positive charge it is not a substance in its own right but is a component of some ionic compounds.It is called the iron III ion.
You obtain 10 millimoles of ferric chloride and dissolve it in a liter of water.
reaction and meachanism of neutral feric chloride with phenols
acetoacetic aster gives ferric chloride test which is a typical test for phenols?
Because it's a test for phenols or enols. Please see the link.

yes
The ferric chloride solution is acidic.
It would test positive because there is a phenol group in vanillin.
Ferric chloride contains the elements iron and chlorine.

Ferric sodium chloride (Na3ClFe) is a compound not a mixture.
Ferric chloride is an ionic compound (and is classified as a salt).
Because aspirin does not contain OH group like salicyclic acid so ferric chloride preferes to react with a compounds that have OH group.
