When is a lake produced in staining?
A mordant combines with a tissue
A dye combines with a tissue
A mordant combines with a stain
A stain combines with a tissue
The correct answer is: A mordant combines with a tissue
A lake in the context of staining refers to a complex formed when a dye (often a colorant) interacts with a mordant, which is a chemical used to enhance the binding of the dye to the tissue. This interaction stabilizes the dye on the tissue, leading to a more vivid and durable color. When a mordant combines with a tissue, it acts as a binding agent that prepares the tissue to attract the dye more effectively. This combination can lead to a more pronounced and stable staining effect. The mordant facilitates a chemical reaction that results in a lake, enhancing the overall visibility of cellular structures under a microscope.
