Question

what happens when an aqueous solution of barium chloride is mixed with an aqueous solution of sodium sulphate? write the equation also.​

Answer 1

Answer:

There is an exchange of ions between the reactants.It is a double displacement reaction.

Na2SO4(aq) +BaCl2(aq)=BaSO4(s)+2NaCl(aq)

Here, the white precipitate of BaSO4 is formed by the reaction of (SO4)2- and (Ba)2+. The other product is sodium chloride which remains in the solution.

Answer 2

Answer:

A white ppt. ( precipitate ) is formed.

Na₂SO₄ ( aq ) + BaCl₂ ( ag ) ⇒  2 NaCl ( aq ) + BaSO₄ ( ↓ )

Doubled Displacement reaction

The reaction in which there is an exchange of ions between the reactants.
