Phenol is used in various applications such as a disinfectant in household cleaners and mouthwash, in chemical peels for skin treatments, as food and cosmetic preservatives, and in the production of carbolic soap. it's also used for the permanent treatment of ingrown toes and fingernails, a procedure known as chemical matrixectomy. moreover, it is utilized in many industries, such as plastic, resin, and cosmetics
Phenol red broth is a test that is differential for gram negative bacteria. It tests for three different things: the the ability of a microbe to ferment glucose, the ability to degrade amina acids, and the ability to produce gas as a byproduct of fermentation. The tube starts out orange colored. If the tube turns yellow, it ferments glucose. If it turns a bright pink or dark red, it degrades amino acids. There is also a tube called a Durham Tube inside of the broth. If bubbles are present inside of the tube, then it produces gas as a byproduct of fermentation.
Phenol red indicates for acidic pH. When the red solution turns yellow it means the solution has a low pH.
For Example:
CO2 dissolves into water and forms carbonic acid which lowers the pH and the solution would turn yellow.
phenol red it self is act as an indicator in fermentation test...
Phenol Red is a very interesting chemical, which leads to intriguing outcomes. It is used in many chemistry labs because it is not particularly dangerous.
A pH indicator. It changes colour from yellow to red as pH increases from 6.6 to 8.0.
Phenol is used in the manufacturing of glue, paint, and other products of that sort. It is highly hazardous.
For big buts.
As a dye indicator.

Phenol is used as a numbing agent, and is contained in products such as Chloraseptic throat spray. It is also used on irritated skin to kill microbes and reduce risk of infections. It is very toxic in high doses, so should be used carefully. The major contraindication for phenol is allergic sensitivity to it.
Phenol is flammable.
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.
What are some examples of Phenol
phenol is used as a odor eliminator

phenol
Phenol is also known as carbolic acid, and is used as a disinfecting agent and topical anesthetic. It may be used to cauterize small wounds and is used in conjunction with calamine (zinc oxide and ferric oxide) as an antipruritic, or anti-itch agent. The phenol most likely is present for its anesthetic effects to calm the itching sensation.
phenol is used as a surgical hand scrub before surgical procedures
Phenol is flammable.
To determine if a bacterium can ferment a particular carbohydrate and determine the end products of that fermentation

Phenol Red is used in this testing because it offers a mid-range pH balance. The color changes from red to yellow when the test is complete.
