What is As2O5? Important knowledge about As2O5.

1. Definition of As₂O₅

As₂O₅, also known as Pentaarsenic pentoxide, or Arsenic Pentoxide in English. It is an organic compound with two Arsenic (As) atoms and five Oxygen (O) atoms bonded together. The atomic mass of As₂O₅ is 213.98, in which the atomic mass of Arsenic is 74.92 and Oxygen is 15.999. The molecular structure of As₂O₅ is formed by two Arsenic atoms linked to five Oxygen atoms through As-O bonds. This generates ions of As^(3-) and O^(2-).
