WebTwo steps in the Gram stain serve to 'trap' crystal violet within the peptidoglycan. First, the mordant forms a complex with the crystal violet, changing its size, making it less likely to escape the cell wall. Second, proper use of decolorizer dehydrates the peptidoglycan, causing the cell wall to shrink, further trapping the crystal violet.
