What is the extinction coefficient of crystal violet?

The extinction coefficient of crystal violet is approximately 89,000 M^(-1)cm^(-1) at a wavelength of 590 nm. This value indicates the molar absorptivity of crystal violet at this specific wavelength, which is commonly used for measuring the concentration of crystal violet in solution using spectrophotometry.


Does crystal violet have a color?

Yes, crystal violet is a triarylmethane dye that appears as a deep purple color when dissolved in water or other solvents.


Explain why crystal violet would not be useful in the negative stain technique?

Negative staining techniques are designed to stain everything BUT the bacterial cells. This allows us to see the cells unstained and helps us observe their morphology (how the cells are shaped and how they group together). The cells have an overall negative charge on their surface, so they naturally attract positive charges. Crystal Violet carries a positive charge, so it would adhere to the surfaces of the cells thus staining the cells (which is not what you want in a negative stain!)


Is crystal violet considered a primary stain in the Gram staining technique?

Yes, crystal violet is considered a primary stain in the Gram staining technique.


Function of crystal violet?

Crystal violet is a hexamethyl also known as methyl violet 10B This is much darker than 2B, and often darker than 6B. It is used in biological stainang particularly gram staining together with safranin and iodine. Crystal violet was also used to treat strept throat. Doctors used to swab it on the back of your throat.


Is crystal violet used as carcinogenic agent?

Crystal violet is not classified as a known carcinogen, but it has been shown to have genotoxic and mutagenic properties in some studies. It is important to handle crystal violet with caution and follow proper safety protocols when working with this compound in the lab.


What color would the bacterial cell have when viewed microscopically after the treatment with ammonium oxalate crystal violet?

The bacterial cell would appear purple when viewed microscopically after treatment with ammonium oxalate crystal violet. The crystal violet binds to the peptidoglycan layer of the cell wall, causing it to retain the purple color even after subsequent washing steps.
