Arsenite
Arsenite (pronunciation: /ˈɑːrsənaɪt/) is a chemical compound that contains the arsenic ion in its trivalent state (As3+). It is one of the primary forms of arsenic found in nature and is often associated with contamination of groundwater and other environmental concerns.
Etymology
The term "arsenite" is derived from the Greek word "arsenikon," which refers to yellow orpiment, a common source of arsenic. The "-ite" suffix is commonly used in chemistry to denote a compound containing a specified element in a lower oxidation state.
