Question

What happens when aqueous solutions of Sodium sulphate and Barium chloride are mixed? Give a balanced

equation for the reaction with state symbols. Name and define the type of chemical reaction involved in the above

change.

Answer 1

this is double displacement reaction.

the balanced equation is

BaCl2 + Na2SO4 = BaSO4 + 2NaCl

bacl2=barrium chloride.

na2so4 =sodium sulphate

The reaction will produce Barium sulfate which is an insoluble white precipitate. Thus the mixture will be clear at the start of the reaction and gradually turn white and cloudy. When solutions of sodium sulphate and barium chloride are mixed, an insoluble solid settles at the bottom of the test tube

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.
