The pigment was originally prepared by making a solution of sodium carbonate at a temperature of around 90 °C (194 °F), then slowly adding arsenious oxide, while constantly stirring until everything had dissolved. This produced a sodium arsenite solution.
Emerald Green, also known as Paris Green, Scheele's Green, Schweinfurt green and Vienna Green, is a synthetic inorganic compound, made by a reaction of sodium arsenite with copper(II) acetate. While it makes a beautiful rich green, the color of the emerald stone, it is highly toxic , due to a main ingredient, arsenic . [ 18 ]

Arsenic biochemistry is the set of biochemical processes that can use arsenic or its compounds, such as arsenate. Arsenic is a moderately abundant element in Earth's crust , and although many arsenic compounds are often considered highly toxic to most life, a wide variety of organoarsenic compounds are produced biologically and various organic ...
Ortho-arsenite contrasts to the corresponding anions of the lighter members of group 15, phosphite which has the structure HPO 2− 3 and nitrite, NO − 2 which is bent. [1] A number of different arsenite anions are known: AsO 3− 3 ortho-arsenite, an ion of arsenous acid, with a pyramidal shape [1] (AsO − 2) n meta-arsenite, a polymeric ...
