Bariumsulfaat - Wikipedia

Bariumsulfaat is het bariumzout van zwavelzuur en heeft als brutoformule BaSO4. De stof komt voor als een wit kristallijn poeder, dat vrijwel niet oplosbaar is in water. Het is ook niet oplosbaar in de traditionele organische oplosmiddelen, maar wel in geconcentreerd zwavelzuur. De in oplossing aanwezige verbinding moet dan echter beschreven worden als bariumwaterstofsulfaat, Ba HSO4 2, omdat …Molmassa: 233,3896 g/mol
