This is a commonly used test to detect the presence of phenolic hydroxyl groups in organic compounds. The reaction between salicylic acid and FeCl3 forms a complex with a purple color, indicating the presence of phenolic groups in the compound.

No, salicylic acid is not an alcohol. It is a type of acid known as a beta hydroxy acid.


2 Why does aspirin not give a positive ferric chloride test as salicylic acid does?

Because aspirin does not contain OH group like salicyclic acid so ferric chloride preferes to react with a compounds that have OH group.


What is the basic chemistry involved in the FeCl3 test for phenylketonuria?

The FeCl3 test for phenylketonuria is based on the reaction between phenylpyruvic acid in urine and FeCl3, forming a green-colored complex due to the chelation of the iron ion. This reaction is specific for detecting phenylketonuria because phenylpyruvic acid is elevated in individuals with this disorder, leading to the formation of the colored complex. The color intensity of the complex formed is directly proportional to the concentration of phenylpyruvic acid present in the sample.


What would be seen if you analyze salicylic acid in FeCl3 test?

If salicylic acid is tested with FeCl3, a violet color will be observed indicative of the presence of phenols in the compound. This test is commonly used to identify the presence of phenolic functional groups in organic compounds.


Is fecl3 acidic salt?

Yes, FeCl3 is an acidic salt because it is a salt composed of a positive iron ion (Fe3+) and three negative chloride ions (Cl-), with the ability to react with water to form hydrochloric acid.

How much gram of fecl3 to be used in preparing fecl3 solution for testing citric acid in semen?

The amount of FeCl3 needed depends on the concentration of the FeCl3 solution required for the test. Typically, a 2-5% solution of FeCl3 is used. To make a 100mL of 2-5% FeCl3 solution, you would need to dissolve 2-5 grams of FeCl3 in distilled water. The exact amount can be calculated using the formula: (desired % concentration/100) x volume of solution needed x molar mass of FeCl3.


What are Electrophiles. I Know They Are Generally Positive Such As H Plus. Would Cl2 slash FeCl3 Be An Electrophile?

Electrophiles are electron-deficient species that are attracted to regions with high electron density. Yes, Cl2 and FeCl3 can act as electrophiles in certain chemical reactions because they can accept electrons from other species. Cl2 can act as an electrophile in a reaction where it accepts electrons to form a covalent bond, and FeCl3 can act as a Lewis acid electrophile due to its ability to accept electron pairs from another molecule.
