Sublimation and solubility of iodine Principle Iodine, whose melting point is at 113.5 °C, evaporates clearly below this temperature. It passes from the solid state directly to the gaseous state. This process is known as sublimation. When iodine vapour cools down, solid crystals form, again without a liquid transitional phase. This process is known as resublimation. Benefits - Stable and safe setup due to solid stand material
- Secure connection of the items by GL screw joint system
Tasks - Show sublimation and resublimation of iodine.
- Investigate the solubility of iodine in oxygen-containing and oxygen-free solvents.
