The lower the phenol coefficient is the stronger the disinfectant is?
No,, the higher the phenol coefficient the stronger the disinfectant
Evaluate the effectiveness of a disinfectant with a phenol coefficient of 40?
A disinfectant with a phenol coefficient of 40 indicates that the chemical agent under study is 40 times as effective as phenol.
Is phenol volatile?
Phenol is flammable.
What are some examples of a phenol?
What are some examples of Phenol
Does phenol react with bromine?
Yes, at room temperature bromine reacts with phenol and forms 2,4,6-tribromo phenol.
The lower the phenol coefficient is the stronger the disinfectant is?
No,, the higher the phenol coefficient the stronger the disinfectant

What is the molar extinction coefficient of Phenol red at 610NM?
Molar extinction coefficient of phenol ret at 610nM is 22 mM-1 cm-1
But not after 5min using phenol coefficient why?
because one bacterium takes 20 minuets to replicate.
Phenol coefficient test in microbiology?
Phenol coefficient test is best known screening test in which potency of a disinfactant is compared with that of phenol. A series of a dilutions of phenol and the disinfactant being tested are prepared. A standard amount of Salmonella tyhpii and Staphylococcus aureus are added to each dilution; the dilutions are then placed in a 20 to 37oC water bath. At 5-minute intervas, samples are withdrawn from each dilution and used to inoculate a growth medium, which is incubated for two or more days and then examined the growth. If there is no growth in the growth medium, the dilution at that particular time of sampling killed the bacteria. The highest dilution that kills the bacteria after 1o min. expousre, but not at 5min. is used to calculate the phenol coefficient. This is done by dividing the resiprocal of the appropriate phenol dilution.
Structure of phenol?
phenol
Is phenol volatile?
Phenol is flammable.
What is the use of chick-Martin test?
Chick martin test is used to estimate the efficacy of a disinfectant. In this test a standard culture of Salmonella typhi, is tested for a fixed period (30 minutes) against various concentrations of phenol solution and various concentrations of the testing disinfectant; the result is expressed as the phenol coefficient, the highest dilution of the given disinfectante that kills bacteria, divided by the highest dilution of phenol that sterilizes the solution, within the measured time.
