Quite many compounds. Phenols are one of the most common group of compounds here. In other words: any compounds containing benzene ring connected to OH group will give you purple color when treated with FeCl3. It seems that if you have FeCL3 sample it is probably impurified by phenolic compounds.
What else can I help you with?
Salicyclic acid gives a positive test with FeCl3?
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.
What is the color of purple bougainvillea indicator if the substance is acidic?
The purple bougainvillea indicator will remain purple if the substance is acidic. Bougainvillea indicator turns pink in basic solutions and remains purple in acidic solutions due to the color change of its pigments in response to pH.
What are the different molecule colors present in the substance?
The substance contains various molecules that each have their own unique color.
Is color intensive or extensive in chemistry?
Color is an intensive property in chemistry, meaning it does not depend on the amount of substance present. The color of a substance remains the same regardless of the quantity.
What is the temperature of purple fire?
Purple fire can reach temperatures ranging from 1,300°C to 1,700°C, depending on the specific elements present in the fire causing it to emit a purple color.
Explain why you would or would not expect to observe a color change if FeCl3 were added to the following?
you would expect a color change in oil of wintergreen because it has an OH group added to the FeCl3 which causes a purple color
If biuret reagent turns purple what substance is present?
Proteins are present when biuret reagent turns purple. Biuret reagent reacts with peptide bonds in proteins, causing the color change.
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.
Salicyclic acid gives a positive test with FeCl3?
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.
What color does biuret reagent turn if lipid is present?
If lipids are present, the solution will turn a purple/violet color.
What color does biuret reagent turn when peptides are present?
Biuret reagent turns purple when peptides are present. This color change is due to a complex formation between the peptides and copper ions in the reagent, which results in the purple color.
What is the color of purple bougainvillea indicator if the substance is acidic?
The purple bougainvillea indicator will remain purple if the substance is acidic. Bougainvillea indicator turns pink in basic solutions and remains purple in acidic solutions due to the color change of its pigments in response to pH.
What happen the color if FeCl3 and KCNS and distilled water mixed?
When FeCl3 and KCNS are mixed in distilled water, a blood-red color solution is formed due to the formation of iron(III) thiocyanate complex. This complex is formed as the Fe3+ ions from FeCl3 react with the thiocyanate ions from KCNS.
Pigment that is present in rhoeo leaf that gives it purple color?
The pigment responsible for the purple color in a Rhoeo leaf is anthocyanin. Anthocyanin is a water-soluble pigment commonly found in plants that appear red, blue, or purple in color.
What color does haxane turn when iodide is present?
conducting that experiment, hexane turned a fushia/purple colour
What is the color of purple bougainvillea indicator if the substance is acid?
acidic - magenta basic - no colour change
Is magenta pink or purple?
Magenta is a shade of purple. An easy way to tell the difference between pink and purple is this; pink is pale red, purple is any combination of red and blue. Because magenta is between red and blue in the color circle, that makes it a purple color.
