In itscompounds, barium has anoxidation stateof +2. The Ba2+ionmay be precipitated from solution by the addition ofcarbonate(CO32−), sulfate (SO42−), chromate (CrO42−), or phosphate (PO43−)anions. All soluble bariumcompoundsare toxic tomammals, probably by interfering with the ...

Barium sulfate is available as white powder or polymorphous crystals. It is stable, odor- less, insoluble, or negligibly soluble in water, and may produce sulfur oxides on burning. It occurs naturally as mineral barite (barytes). It has wide use as an inert i ller pigment extender in pain...
A water-soluble barium salt can be easily produced from barium sulfate which is insoluble in water and acid. The process is suitable e.g. for dissolving barium chromate in sulfuric acid to produce chromic acid solution and converting by-produced barium sulfate to a water-soluble barium salt ...
