Arsenate - Ions


  • In strongly acidic conditions it exists as arsenic acid, H3AsO4;
  • in weakly acidic conditions it exists as dihydrogen arsenate ion, H2AsO4−;
  • in weakly basic conditions it exists as hydrogen arsenate ion HAsO42−;
  • and finally, in strongly basic conditions, it exists as the arsenate ion AsO43−.
