Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. The Physical Properties of Iodine are as follows:
- Color : Violet black. A sgray solid that changes into purple vapors when heated
- Luster : Has a shine or glow
- Odor : Strong, harsh odor
- Crystalline structure : Rhombic
- Density : Heavy
Iodine Properties - What are the Chemical Properties of Iodine?
What are the Chemical Properties of Iodine? They are the characteristics that determine how it will react with other substances or change from one substance to another. The better we know the nature of the substance the better we are able to understand it. Chemical properties are only observable during a chemical reaction. Reactions to substances may be brought about by changes brought about by burning, rusting, heating, exploding, tarnishing etc. The Chemical Properties of Iodine are as follows:
- Chemical Formula : Hg
- Toxicity : Poisonous halogen
- Oxidation : It does not combine directly with oxygen
- Compounds : With hydrogen it forms hydrogen iodide, which in water solution becomes hydriodic acid. Its compounds are used in medicine and photography and in dyes
- Corrosion : Highly corrosive
- Reactivity with water : Dissolves only slightly in water
- Reactivity with heat : Moves from the solid to the vapor state (sublimation)
