What state of matter is phenol red solution?
A solution of phenol red is a liquid.
What increase absorbance of phenol in ethanol?
Increasing the amount of phenol in the solution
What are identification tests of phenol?
You add a specific ionic compound in a solution to determine if phenol or any of its derivatives are present. Ferric chloride (FeCl3) for example, can be used for such tests. Basically, when you mix the solution with the compound, the ions will interact with the phenol molecules or groups, and as a result, the solution will briefly change color. If there is no colour change in the solution, this suggest there is no phenol or phenol-based molecules in your solution.
Function of phenol DNA extraction?

Why only phenol dissolve in aqueous NaOH?
Phenol is not dissolved in a sodium hydroxide solution; having the characteristics of a weak acid phenol react with NaOH.
How do you make a solution of phenol red?
Boil red cabbage in water to make phenol red. This works well depending on how long you boil it will determine the strength of the solution.
What happened when impurity is added in phenol water system?

Suggest a chemical test(s) to distinguish ethanol and phenol. Include the reagents reaction conditions and observations. And the equation?
Phenol solution, or phenol directly from the manufacturer?If the phenol is in the form it comes in from the factory, no chemical test is necessary. Phenol is a white crystalline solid.If it's dissolved in water, the easiest test is pH. Phenol solution is more acidic than ethanol. So...whatever you use for a pH test will do ya.
What happened to phenol with Iron III chloride reagent?
"Addition of aqueous iron III chloride to a phenol gives a colored solution. Depending on the structure of the phenol, the color can vary from green to purple.
How cool phenol water solution?
Just add ice cubes.
What happens if you swallow the phenol red indicator solution?
Your throat will be irritated and your voice will turn hoarse.
