Beryllium Arsenates

Beryllium Arsenates Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  Beryllium arsenate salts are less stable than those of magnesium and readily form basic salts. This is due to the fact that Be²⁺ preferentially forms hydroxy complexes of the type, Be(OH)⁺ in association with water molecules. Species such as Be2(OH)³⁺ and Be3(OH)3 ²⁺ are known to exist. The hydroxylation reaction has been given as:
  xBe²⁺ + yH2O ? Bex(OH)y ^2x-y+ + yH⁺
  where x and y can vary from 1 to 8. Species such as Be3(OH)7³⁺ and Be4(OH)8⁴⁺ are known. Thus, the prior literature may be in doubt as to exact formulas for beryllium compounds prepared from aqueous solutions.
