What are
the Properties of Iodine? Definition of Iodine
What is the definition of
Iodine? It is a lustrous, violet-black, corrosive, poisonous halogen element
having radioactive isotopes. The
Physical and
Chemical Properties are the
characteristics of a substance, like Iodine, which distinguishes it from any
other substance. Most common substances, like Iodine, exist as
States of Matter as solids, liquids, gases and plasma. Refer to the article on
Iodine for additional information and facts about this substance.

What are the Physical
Properties of Iodine? The Physical properties of Iodine are the characteristics
that can be observed without changing the substance into another
substance. 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:

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) |
