Heating iodine

WebThus, the notion that upon heating iodine only sublimes, but does not melt is present in many chemistry textbooks, teachers lectures and, therefore, in students minds and may be considered as one of the widespread misconceptions in chemistry teaching. Web5 de nov. de 2024 · Iodine crystals slowly sublime at room temperature, and when heated they turn into deep-purple vapors. What happens when iodine evaporates? When melting is complete the temperature resumes its rise until it gets to 184.3 oC (point 3), and the liquid begins to evaporate. When vaporization is complete, the temperature again begins rising.
