When aqueous barium chloride and aqueous sodium sulfate are mixed, a dense white precipitate of barium sulfate is formed.
What is the correct ionic equation, including state symbols, for this reaction?
Ba2+(aq)+SO42−(aq)→BaSO4(aq)\text{Ba}^{2+}(\text{aq}) + \text{SO}_4^{2-}(\text{aq}) \rightarrow \text{BaSO}_4(\text{aq})Ba2+(aq)+SO42−(aq)→BaSO4(aq)
Ba2+(aq)+SO42−(aq)→BaSO4(s)\text{Ba}^{2+}(\text{aq}) + \text{SO}_4^{2-}(\text{aq}) \rightarrow \text{BaSO}_4(\text{s})Ba2+(aq)+SO42−(aq)→BaSO4(s)
Ba+(aq)+SO4−(aq)→BaSO4(s)\text{Ba}^{+}(\text{aq}) + \text{SO}_4^{-}(\text{aq}) \rightarrow \text{BaSO}_4(\text{s})Ba+(aq)+SO4−(aq)→BaSO4(s)
Ba2+(s)+SO42−(s)→BaSO4(s)\text{Ba}^{2+}(\text{s}) + \text{SO}_4^{2-}(\text{s}) \rightarrow \text{BaSO}_4(\text{s})Ba2+(s)+SO42−(s)→BaSO4(s)
