TRIIODIDE Meaning and
Definition
-
Triiodide is a chemical compound comprised of three atoms of iodine, denoted by the symbol I, and has a negative charge of -1. The compound is formed when three iodine atoms combine together. It is classified as a polyatomic ion due to its triatomic structure. The triiodide ion is most commonly represented as I3-.
Triiodide is an anion that exhibits strong reducing properties and is highly reactive. It is soluble in organic solvents like ether but not in water, making it useful for certain chemical reactions that require an inert solvent. Its solubility in water can be enhanced by the addition of specific cations.
The compound finds applications in various fields of science, such as in redox reactions and coordination chemistry. In analytical chemistry, triiodide is employed as a reagent to detect the presence of starch in solutions, due to the formation of a deep blue complex. It can also be utilized in the synthesis of certain organic compounds.
Triiodide is typically produced by the reaction of an iodide salt, such as potassium iodide, with an iodine source, such as molecular iodine or iodine monochloride. The resulting compound is a dark colored solid with a distinctive odor. Triiodide is often stored and handled under specific conditions due to its reactivity.

Etymology of TRIIODIDE
The word "triiodide" is derived from the combination of two parts: "tri" and "iodide".
1. "Tri-" is a prefix meaning "three". It comes from the Latin word "tres" meaning "three".
2. "Iodide" is a noun that refers to a chemical compound containing iodine. The term "iodide" comes from the element's name "iodine" combined with the suffix "-ide", which is commonly used in chemistry to indicate an ion or compound formed from an element.
When combined, "tri-" and "iodide" form "triiodide", a term used to describe a compound consisting of three atoms of iodine.
