Hydroquinine functions as what in staining protocols?

Explanation:
Hydroquinone acts as a reducing agent in staining protocols. It donates electrons to silver ions (Ag+), reducing them to metallic silver (Ag0) that deposits in the tissue to form the visible image. This development step is about reducing metal ions to create the stain, not about oxidizing something, coloring with a dye, or differentiating structures.
