METAARSENITE Meaning and
Definition
-
Metaarsenite is a chemical compound that refers to the salts or esters of metaarsenious acid. It is a term used in chemistry to describe a class of substances that contain the metaarsenite ion, which is represented by the chemical formula AsO2^3-. The metaarsenite ion is composed of three oxygen atoms, each bonded to a central arsenic atom.
Metaarsenite compounds are typically formed by the reaction of metaarsenic acid or its corresponding oxide with a base or a metal. These compounds exhibit distinctive chemical characteristics and can have various applications in both industrial and laboratory settings. For instance, they can be involved in the production of pigments, glass, ceramics, and other materials due to their ability to impart specific colors and properties.
From a structural standpoint, metaarsenite ions possess a trigonal pyramidal geometry. This geometry is a result of the three oxygen atoms arranged symmetrically around the central arsenic atom. The metaarsenite ion is considered to be a tetrahedral isomer of the more common orthoarsenite ion.
Overall, metaarsenite is an essential chemical entity with diverse applications in various fields. Its understanding and study contribute to the advancement of industries such as materials science, environmental sciences, and inorganic chemistry.
Etymology of METAARSENITE
The word "metaarsenite" is derived from the combination of two Greek roots: "meta-" and "arsenikos".
1. "Meta-" (μετα-): In Greek, "meta-" is a prefix that means "after" or "beyond". It is commonly used to indicate a change or transformation from the original state.
2. "Arsenikos" (ἀρσενικός): This Greek word means "of or pertaining to arsenic". Arsenic is a chemical element known for its toxicity.
When combined, these roots form "metaarsenite", which refers to a chemical compound that is related to or derived from arsenic but has undergone a transformation or alteration from its original state.
