When present in compounds barium exists usually in the Ba 2+ , divalent state. Barium dissolves in most aqueous acids except sulfuric acid, due to the formation of an insoluble protective layer of barium sulfate.
Most insoluble ions include OH-, CO3(2-), PO4(3-), S(2-). These, if they are soluble, are most likely weak and can bond and split in whatever solution it happens to be in. A â¦ ll soluble ions would override these but Barium is not one of those.So, no.One noteworthy thing about Barium is that it is insoluble with SO4(2-) despite SO4(2-) being a soluble ion. + 5 others found this useful. â¦ ll soluble ions would override these but Barium is not one of those.
