Yellow
Phenol red is made by condensation of Phenol and saccharine.pH below 6.8 = YellowpH above 8.2 = Red/FuschiaGradually turns from yellow to red/fuschia (pH between 6.8 and 8.2 = Pinkish)
Which compound decolorizes the color of permanganate
red
Phenol red is a pH indicator. The baking soda is not changing color, but the phenol red is.
after preparing the white phenol, addition of any color shall turn to the respective color. Like lemon salt shall turn the phenol in to yellow in colour.
Phenol Formaldehyde Resin in liquid phase appear as rides brown.
it becomes an orange-red color
green
yellow
"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.
Yellow
It turns a yellow-ish color when CO2 is added.

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.
