Why should we acidify the sodium carbonate extract?
Acidifying the sodium carbonate extract helps to convert any remaining phenol into the non-polar phenol form, which is more easily extracted with an organic solvent. This step also helps to separate the phenol from other compounds in the mixture, making it easier to purify and isolate the phenol. Additionally, acidification can help to adjust the pH of the solution to a range that is more suitable for subsequent reactions or analyses.
How chloroform makes three phases of RNA DNA and protein in phenol chloroform extraction?
Chloroform is a solvent that helps to separate the three phases in phenol-chloroform extraction by disrupting the interactions between the biomolecules. RNA, DNA, and proteins have different affinities for phenol, chloroform, and water, leading to their partitioning into separate phases based on their solubility. Chloroform enhances the separation by forming distinct layers that can be easily separated, allowing for the isolation of the desired biomolecules.
Can you get phenol from carbolic acid?
Phenol and carbolic acid are actually the same compound. "Carbolic acid" is an older, colloquial term for phenol.
What increase absorbance of phenol in ethanol?
Possible factors that can increase the absorbance of phenol in ethanol are: increasing the concentration of phenol in the solution, using a higher path length cuvette for measurement, and selecting a wavelength for measurement where phenol has a higher molar absorptivity coefficient.
What color is phenol red as a base?
Phenol red is red in its basic form.
What is the best solvent for phenol for use in Gas Chromatography?
water
Function of phenol DNA extraction?
Phenol is used in DNA extraction to separate DNA from proteins and other contaminants. It denatures proteins and disrupts cell membranes, allowing DNA to be separated and purified. The phenol acts as an organic solvent to extract DNA from aqueous solutions.
What is 80 percent phenol?
80% phenol solution is a mixture containing 80% phenol and 20% water or another solvent. Phenol is a chemical compound used as a disinfectant, antiseptic, or chemical intermediate in various industries. It is important to handle this solution with care due to its corrosive and toxic nature.

Structure of phenol?
phenol
What is the derivative of Phenol?
The derivative of Phenol is Carbolic acid.
Does phenol react with bromine?
Yes, at room temperature bromine reacts with phenol and forms 2,4,6-tribromo phenol.

What is phenol used for in medical practices?
phenol is used as a odor eliminator
What is a substituted phenol?
Any phenol that has substituents in a 1, 3 configuration.
Why phenol does not dissolve in water when excess?
Phenol is slightly soluble in water due to hydrogen bonding between the hydroxyl group of phenol and water molecules. However, when excess phenol is added, it disrupts the hydrogen bonding network of water molecules, making it less soluble. This is because phenol-phenol interactions become stronger than phenol-water interactions, leading to precipitation.
