Pronunciation: [ˈɑːsənˌa͡ɪt] (IPA) 
Arsenite is a chemical compound of arsenic in which the element has a -3 oxidation state. The word arsenite is spelled /ɑːsɪnaɪt/, with the stress on the second syllable. The letter 'a' in the first syllable is pronounced as a long vowel sound /ɑː/, while the second syllable is pronounced with a short vowel sound /ɪ/. The letters 's' and 'n' in the middle of the word are pronounced as a single syllable, represented by /snaɪt/.
Arsenite is a noun that refers to a chemical compound containing arsenic in its +3 oxidation state. It is derived from the element arsenic and carries a negative ionic charge. Arsenic is a naturally occurring, toxic element found in rocks, minerals, and soil. When combined with other elements, it forms various compounds, and arsenite is one of them.
Arsenites are typically formed by reacting arsenic trioxide (As2O3), a highly toxic substance commonly known as arsenic, with a reducing agent. Arsenite compounds are commonly found in various industries, particularly in the production of certain pigments, semiconductors, and glass. They also have limited use as herbicides and insecticides in agriculture.
In aqueous solution, arsenites exhibit a wide range of colors, from colorless and pale yellow to white and light green, depending on the specific compound. These compounds are known for their high toxicity and ability to accumulate in living organisms, making them highly harmful to human health and the environment. Prolonged exposure to arsenites can cause various health issues, including skin problems, respiratory difficulties, cardiovascular disorders, and even cancer.
Moreover, arsenites have been historically used as poison due to their toxicity. However, these compounds have also found applications in analytical chemistry as reagents and as inputs in various scientific studies. With the increased awareness of their dangers, strict regulations have been put in place to control their usage and ensure proper handling to minimize health risks.

The word "arsenite" is derived from the chemical element "arsenic". "Arsenic" originated from the Latin word "arsenicum", which, in turn, came from the Greek word "arsenikon" meaning "yellow orpiment". The term "arsenikon" likely originates from the Persian word "zarnīkh" meaning "yellow orpiment".
