Would water be a suiable solvent for every dye?
-Cationic dyes (basic dyes) are soluble in polar solvents such as water, alcohols -Nonionic Fat-soluble dyes line metal-free azo and anthraquinone dyes are soluble in aromatic and aliphatic hydrocarbons. -Metal-complex dyes are normally soluble in alcohols, ketones, glycoethers
What are the problems with synthetic dyes?
its a synthetic dye is used 2 colour putkis and pels. this is the advantage.
Why are basic stains attracted to the bacteria itself?
The bacterial cell wall has a negative charge. The basic stain has a positive charge. Since they have opposite charges, the bacterial cell wall and the basic stain are attracted to each other; hence the basic stain dyes the bacteria.
Can dyes or other methylene blue be used for direct staining?
Crystal violet, basic fuchsin, and safranin are all dyes which can be used in direct staining because they are cationic which means that they are positively charged. These dyes which are positively charged will react to the bacterial cell wall because the cell wall is negatively charged resulting in a basic stain.
Why azo dyes are resticted for textile dyeing printing?
The azo dyes that are restricted for textile use have been so restricted because they cause skin hypersensitivity and allergies. Not all azo dyes are so restricted--there are eleven azo dyes that are approved for use in food.
What types of synthetic dyes are there?
There are may types of dyes but these are the ones I know of. Acid dyes Azoic dyes Basic dyes Chrome dyes Mordant Developed dyes Direct dyes Disperse dyes Reactive dyes Sulphur dyes Vat dyes Raw fibres Velour cloth and furs Batik Tie dyeing BY MAX TURNER

What one of these leucocytes stain both acidic and bacic dyes?
Neutrophils stain both acidic and basic dyes
Why microbiologists use stains on cells?
Basic dyes have positively charged chromophore; thus, there target of binding affinity is the specimen or the microorganism which has a negatively charged cell wall. Through this, basic dyes can penetrate and making it an efficient stain for microorganisms.
What is the difference between acidic dye and basic dye?
basic dyes are more effective for bacterial staining than acidic dyes because basic dyes have a positive charged chromogen. Bacterial nucleic acids and certain cell wall components carry a negative charge that strongly binds to the cationic chromogen.
Does a reticulocyte stain with cresyl blue?
Stain with basic dyes cytoplasm shows blue precipitates
What are the problems with synthetic dyes?

What is basophilia?
Basophilia is the condition of being basophilic - describing biological tissue which stains readily with basic dyes.
Which of the following is an example of an acidic stain?
Basic dyes: Crystal violet, Methylene blue, Malachite green, Safranin. Acidic dyes: Nigrosin, Congo red
White blood cell with dark-staining granules that have an affinity for basic dyes?
The description matches eosinophils, a type of white blood cell. Eosinophils are characterized by dark-staining granules that can be visualized under a microscope by basic dyes such as eosin. They play a role in allergies and parasitic infections.
Can red 40 cause drunkeness?
Red #40 can trigger behavior problems. In Europe, warnings are on products with this and other synthetic dyes made from petroleum. In March, the FDA is holding hearings on food dyes.
Bacterial cell Acidic dyes carry what charge?
They carry negative charge and are repelled by negatively charged cell structures. Basic dyes are opposite (carry positive charge) and are attracted to negatively charged cell structures.
