Basic dyes:
Crystal violet, Methylene blue, Malachite green, Safranin.
Acidic dyes:
Nigrosin, Congo red
# The pH will determine if the bacteria will have a particular charge. If the chromophore is a positive ion like the methylene blue in the equation shown in the reading, the stain is considered a basic stain; if it is a negative ion, it is an acidic stain. Most bacteria are stained when a basic stain permeates the cell wall and adheres by weak ionic bonds to the negative charges of the bacterial cell.
yes you can and the stain can change colors if there is a juice stain for example thats red and a grass stain the stain color could change
acidic character
You can remove the green stain on metal by treating the rust stains with a cleaning agent such as a lime remover or some kind of harsh acidic substance.
blood
Neutrophils stain both acidic and basic dyes
Acidic

Acidic,basic and neutral stains
Yes. Eosin and acid fuchsin are also acidic dyes like nigrosin.

It is basically use to stain leukocytes,maleria prasite and trypanosomas. leisman stain contain 1st methylene blue dye, a basic dye, which gives color to an acidic component.2nd eosin dye,an acidic dye ,which gives color to a basic component. These dye differentiat the different component of blood.

Since there is no heat fixing or strong cemicals are used the bacteria are less distorted
acidic character
Acidic dyes are negatively-charged dyes. Since bacteria are also negatively-charged, they will repel the acidic dyes. So, instead of staining the bacterium itself, it will be the background that will be colorized....
it is an example ostrawberry jam
