# 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.
Acidic oxides form acids with water: eg SO2 + H2O --> H2SO3 Basic oxides form basic salts (alkaline) with water: eg. CaO + H2O --> Ca(OH)2 Amfotheric oxides have both acidic and base properties: eg. Aluminium oxide is an amphoteric oxide, which means that it displays both acidic (1) and base (2) properties: 1. Al2O3 + H2O --> 2 Al(OH)2- + 2 H+ 2. Al2O3 + H2O --> 2 Al3+ + 3 OH-
Basic dyes: Crystal violet, Methylene blue, Malachite green, Safranin. Acidic dyes: Nigrosin, Congo red
A stain is temporary whereas dyes are permanent and can be removedonly after cell wall destruction.
Laundry Detergent Gets Rid Of Smells And Odors And Stain Removers Get Stains Out.
Neutrophils stain both acidic and basic dyes
Acidic,basic and neutral stains

The difference between Wright Stain and Giemsa Stain is the intensity of the stain. The Giemsa Stain provides a better stain intensity than the Giemsa stain.
its the difference in cell wall of both the type of bacteria
Sure, any basic stain can be used for simple, direct staining.
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
Sudan black B stainThis stain distinguishes between acute lymphoblastic leukemia (cells stain positive) and acute myeloblastic leukemia (cells stain negative).
Basic dyes: Crystal violet, Methylene blue, Malachite green, Safranin. Acidic dyes: Nigrosin, Congo red
