Question

what happened when an aqua solution of sodium sulphate reacts with aqua solution of Barium Chloride state the physical condition of reactant in which the reaction between them will not take place write the balanced chemical equation for the reaction and name the type of reaction​

Answer 1

when tgey react NaCl and BaSO4 will formed and in solid state they will not react and its a double displacement reaction

Answer 2

when sodium sulphate reacts with barium chloride, sodium displaces barium to form sodium chloride.

this reaction is called double displacement reaction Bcz this reaction takes place by the exchange of ions .

Na2SO4 + BaCl2 -----> NaCl + BaSO4
