How does Nigrosin work?
Nigrosin is a negatively charged acidic dye that is commonly used in staining techniques in microbiology and histology. It works by binding to positively charged structures in cells, such as nucleic acids, giving them a dark coloration which aids in visualization under a microscope.
Is turpentine basic or acidic?
Turpentine is slightly acidic, with a pH around 4-6. It is not strongly acidic, but it is not considered basic either.

Why does nigrosin not stain bacterial cells?
Nigrosin is an acidic stain composed of large molecules that are repelled by the negatively charged bacterial cell surface. Bacterial cells typically have a negative charge due to components like lipopolysaccharides in their cell walls, which repel the negatively charged nigrosin dye, preventing it from staining the cells.
