Sodium dihydrogen arsenate Sodium dihydrogen arsenate Sodium dihydrogen arsenate is the inorganic compound with the formula NaHAsO. Related salts are also called sodium arsenate, including NaHAsO (disodium hydrogen arsenate) and NaHAsO (sodium dihydrogen arsenate). Sodium dihydrogen arsenate is a colorless solid that is highly toxic. The salt is the conjugate base of arsenic acid: In the laboratory, it is prepared in this way, crystallizing from a hot saturated aqueous solution, where it is highly soluble when hot (75.3 g in 100 mL at 100 °C). It is obtained as the monohydrate. Upon heating, solid NaHAsOHO, loses water of crystallization and converts to the
Lithium ion manganese oxide battery Lithium ion manganese oxide battery A Lithium ion manganese oxide battery is a lithium ion cell that uses manganese dioxide, , as the primary cathode material. They function through the same intercalation/de-intercalation mechanism as other commercialized secondary battery technologies, such as . They are a promising technology as their manganese-oxide components are earth-abundant, inexpensive, non-toxic, and provide better thermal stability. One of the more prominent compounds is , a lithium-manganese-oxide based material with a spinel structure (space group Fd3m). In addition to being a cheap and non-toxic alternative material, the spinel structure of provides a three-dimensional framework for the insertion
