Question: Which is the correct net ionic equation that describes when a calcium chloride aqueous solution is added to a sodium sulfate aqueous solution? 1. Ca2+(aq)

Which is the correct net ionic equation that describes when a calcium chloride aqueous solution is added to a sodium sulfate aqueous solution? 1. Ca2+(aq) + 2Cl-(aq) + 2 Na+(aq) + SO^2-4(aq) -> Ca SO4(s) + SCl-(aq) + 2Na+(aq)

2. Ca2+(aq) + 2Cl-(aq) + 2NA+(aq) + SO^2-4(aq) -> Ca2+(aq) + 2NaCl(s) + SO^2-4(aq)

3. CaCl2(aq) + Na2SO4(aq) -> CaSO4(s) + NaCl(s)

4. Ca2+(aq) + SO^2-4(aq) -> CaSO4 (s)

5. Na+(aq) + Cl-(aq) -> NaCl(s)
