An aqueous solution of barium chloride, BaCl2(aq)\text{BaCl}_2(\text{aq})BaCl2(aq), is mixed with an aqueous solution of sodium sulfate, Na2SO4(aq)\text{Na}_2\text{SO}_4(\text{aq})Na2SO4(aq). A white solid is formed according to the chemical equation:
BaCl2(aq)+Na2SO4(aq)→BaSO4(s)+2NaCl(aq) \text{BaCl}_2(\text{aq}) + \text{Na}_2\text{SO}_4(\text{aq}) \rightarrow \text{BaSO}_4(\text{s}) + 2\text{NaCl}(\text{aq}) BaCl2(aq)+Na2SO4(aq)→BaSO4(s)+2NaCl(aq)What type of reaction is this?
Neutralisation
Precipitation
Displacement
Thermal decomposition
