What will be the color change of crystal violet at different pH?
Crystal violet is a pH indicator that changes color depending on the pH of the solution. At lower pH values (acidic conditions), crystal violet appears yellow, while at higher pH values (alkaline conditions), it changes to a blue color. This color change makes it useful for determining the pH of a solution within a specific range.
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.
What colour does the indicator go when in alkili?
The universal indicator turns blue or violet in alkaline solutions.
What could be a possible substitute for cresol red to prepare a hydrogen carbonate indicator?
Cresol red is a chemical dye used as an indicator for instruments that measure pH levels. It has a pH range of 0.5 to 2.5 and transitions from rose to brown to yellow. The closest substitute in terms of pH range?æwould be the Crystal violet, also known as Gentian violet. It has a pH range of 0.8 to 2.5 and transitions from yellow to blue to violet.
What is the charge of crystal violet?
The charge of crystal violet is positive.
Is the crystal violet test result positive or negative?
The crystal violet test result is positive.
What is the secondary stain in gram stain procedure?
It is crystal violet & stains all cells purple.

What is the name of the acide base color indicator found in MacConkey agar?
Lac+ bacteria is acid base color indicator that lowers the pH of the MacConkey agar. The MacConkey agar contains neutral red dye, lactose, peptone, and crystal violet dye.
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.
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.
