- barium carbonate
- barium(II) carbonate
The oxidation number of barium in barium carbonate is 2.
Synthesis
Barium carbonate is made by the addition of ammonium bicarbonate to BaCl2 in cold water. As barium carbonate is essentially insoluble, it precipitates readily.
BaCl2(aq) + (NH4)2CO3(aq) → BaCO3(s) + 2NH4Cl(aq)
