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.
Basic dyes have a chromophore that has a positive charge which is attracted to the negative charges on the cell wall of bacteria. Negative stains are negatively charged, so they are repelled from the cell walls of bacteria. Negative stains will stain the background instead of staining the cell directly.
A acidic dye carries a negative charge. It has lost a hydrogen. A basic dye carries a positive charge: it has either gained a hydrogen or lost a hydroxide.
Because basic dyes are positvely charged while most surfaces of bacteria are negatively charged
because basic dyes are positively charged while most surfaces of bacteria are negatively charged.
that most cells are negatively charged.
No. It is basic. No. It is basic.
yes malachite is a basic dye and used in dyeing of acrylic fabric. it is also known as basic green.
A basic dye used in gram staining is crystal violet.
it is a basic dye that will stain the cells. That makes it a positive stain.

saponin is not a dye rather it is a surfactant produced by plant.
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.

yes. it is an acidic dye.....
Red color in acidic solutions and blue color in basic solutions.
sulphur dye is made by sulphur linkage &vat dye made by ketone linkage. thus sometimes sulphur dye are used for basic dye in respect to mordant. that is called topping. when we shall break insoluble vat dye,then we shall get pigment.
One will dye your hair blonde and one will dye your hair brown.
The difference between dyed and un-dyed kerosene is the dye its self. The dye used in kerosene can cause wicks and appliances to clog.
Not much but temp is supposed to effect penetration, Just follow instructions per dye maker
