What are the classification of stains?
1. On the basis of origin, stains can be classified as natural and synthetic. 2. On the basis of chemical behavior, dyes are classified as acidic, basic and neutral.
What are basic stains?
Basic stains, such as methylene blue, Gram safranin, or Gram crystal violet are useful for staining most bacteria. These stains will readily give up a hydroxide ion or accept a hydrogen ion, which leaves the stain positively charged.
