Why is it necessary to use iodine during this investigation
The iodine in the gram stain serves as a mordant or fixative.
Elemental iodine is a solid. But it is a volatile solid in that chemists will use solid iodine in a chamber to "iodine stain" substances in thin layer chromatography. Thus iodine is like having a volatile solid.
