Why acetoacetic ester gives ferric chloride test?
Acetoacetic ester gives a positive ferric chloride test due to the presence of the beta-keto group in the molecule. The keto group reacts with ferric chloride to form a colored complex, producing a characteristic color change that indicates the presence of the keto group in the compound.
Is vanillin positive in a ferric chloride test?
Yes, vanillin is positive in a ferric chloride test. When vanillin reacts with ferric chloride, it forms a colored complex that gives a characteristic blue or green color, indicating the presence of phenolic compounds.
Why is ferric chloride used in modified borntrager's test?
Ferric chloride is used in modified Borntrager's test as a reagent to detect the presence of phenolic compounds in a sample. It forms a colored complex with phenols, which helps in identifying the presence of phenolic substances in the test solution.
What is the equation when iron reacts with chlorine giving ferric chloride or ferrous chloride?
Ferric or Iron (III) = Fe3+Chloride = Cl-Fe3+ + Cl- = Fe2Cl
Why would vanillin test positive in a ferric chloride test?
Vanillin contains aromatic groups that can form colored complexes with ferric chloride, resulting in a positive test by producing a color change. This reaction is commonly used to detect the presence of phenolic compounds like vanillin in a sample.

What is the purpose of the ferric chloride test and how is it used in chemical analysis?
The purpose of the ferric chloride test is to detect the presence of phenols in a substance. In chemical analysis, ferric chloride is used as a reagent to react with phenols, producing a color change that indicates the presence of these compounds. This test is commonly used in organic chemistry to identify and quantify phenols in various samples.
How is a positive test for phenols using ferric chloride recognized?
A positive test for phenols using ferric chloride is recognized by the formation of a colored complex. When phenols react with ferric chloride, a deep purple or blue color indicates the presence of phenols. This color change occurs due to the formation of an iron-phenol complex.
Is ferric chloride neutral?
No, ferric chloride is not neutral. It is an acidic compound.
What is the pH value of ferric chloride?
The ferric chloride solution is acidic.
What colour does Ferric chloride burn?
Ferric chloride burns with a blue/green flame.
Is ferric sodium chloride a mixture or not?
Ferric sodium chloride (Na3ClFe) is a compound not a mixture.
What type of compound is ferric chloride?
Ferric chloride is an ionic compound (and is classified as a salt).
What is the recommended method for safely neutralizing ferric chloride using a ferric chloride neutralizer?
The recommended method for safely neutralizing ferric chloride is by using a ferric chloride neutralizer. This substance helps to safely and effectively neutralize the acidic properties of ferric chloride, making it less harmful to the environment and easier to dispose of.
Why ferric chloride test is not used to identify alcohols?
Because it's a test for phenols or enols. Please see the link.
