2,4,6-trinitrophenol

phenol red turns yellow because it reacts to carbonic acid, which is a product of carbon dioxide mixing with H2O, or water. Phenol red is a Ph indicator, but not a very good one, so it reacts to strong acids (yellow orange) and strong bases (pink) hope this helped!
Its a base and reacts with HCl to form a salt : para-Hydroxyanilinium Chloride
HX ---> H+ + X- Keq = [H+][X-]/[HX]
Yes, at room temperature bromine reacts with phenol and forms 2,4,6-tribromo phenol.
The substitution reactions of phenol are easier than benzene, phenol directly reacts with bromine and gives tribromo phenol while benzene requires FeCl3 as a catalyst and gives mono bromo phenol.
2,4,6-trinitrophenol
Hinsberg reagent is used for amines.
Phenol reacts with the chemical components of whatever surface it is touching, which breaks bonds in the surface and causes chemical burn.

2 bromophenol, 4 bromophenol and hydrogen bromide are formed
Phenol is so weakly acidic that it cannot react with metals low in the electrochemical series. Also, phenol reacts only with Sodium metal and no other. Hence, it does not react with Magnesium at room temperature.

Iron (III) Chloride reacts with the Phenol group. Ibuprofen and Naproxen do not have a phenol group. Acetaminophen, on the other hand, does have a phenol group with would indicate a positive test (purple color change) with in the presence of Iron (III) Chloride.
HX Draw was created in 1911.
