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.
Polycarbonate is one of those materials that was discovered by accident. A chemist named Einhorn was trying to make cyclic carbonates by reacting phosgene (a very dangerous chemical later used as a chemical warfare agent) with hydroquinone (a phenol used largely as a film developing agent) and got an insoluble solid. Tests at Bayer in the 1950s to find the best phenol led to the discovery the phenol used in epoxy, bisphenol A, was the right phenol to use in polycarbonate.
Additional tests that can be conducted to assist in the identification of an unknown organism include biochemical tests, genetic sequencing, and serological tests. These tests can provide valuable information about the organism's metabolic pathways, genetic makeup, and antigenic properties, helping to narrow down its identity.
The derivative of Phenol is Carbolic acid.
Biochemical tests commonly used for the identification of Zymomonas species include fermentation of sugars like glucose and fructose, production of ethanol, utilization of different carbon sources, and enzyme activities such as catalase and oxidase tests. Additionally, molecular techniques like PCR and sequencing can also be employed for accurate identification.
Yes, at room temperature bromine reacts with phenol and forms 2,4,6-tribromo phenol.
Common biochemical tests for identifying cyanobacteria include testing for the presence of chlorophyll a, phycocyanin, and phycoerythrin pigments. Additionally, assessing the ability to fix atmospheric nitrogen (nitrogen fixation) and conducting tests for the presence of gas vesicles are also used for identification purposes. Molecular techniques like PCR and sequencing can also be employed for more accurate identification.
It means that it tests positive for either aldehyde, alkene, or phenol functional groups.
Phenol is found in various products such as disinfectants, antiseptics, and certain medications. It can be identified by checking the ingredient list on the product label or by conducting a chemical test for phenol.
The most common biochemical tests are gram stain, oxidase, catalase and coagulase tests. However, there are literally hundreds of biochemical tests that are commonly used to identify bacteria. For further information, check out MicrobeID.com, where you can find identification methods, keys, probabilistic databases, selective and differential media guides, as well as book reviews releated to bacterial identification. I would also recommend Bergey's Manual of Deterministic Bacteriology.

The ferric chloride test: Ethanol does not react with ferric chloride, while phenol forms a purple color when mixed with ferric chloride. The bromine water test: Ethanol does not react with bromine water, while phenol decolorizes bromine water due to its reducing properties.
