The mordant in the Gram stain is iodine. It is used to enhance the crystal violet stain and lock it into the cell wall of Gram-positive bacteria. After the iodine is added, the slide is washed with alcohol to decolorize Gram-negative bacteria, which will then be counterstained with safranin. Therefore, the correct sequence of the Gram stain reagents is crystal violet, iodine, alcohol, and safranin.
