Double Displacement Reaction

Procedure:

• Take 2ml of sodium sulphate solution in a test tube.
• Take 1ml of barium chloride solution in another test tube.
• Add barium chloride solution to sodium sulphate solution.
• Observe the change.

• To pour barium chloride solution (BaCl2) into the test tube, drag the dropper towards it.
• To pour sodium sulphate solution (Na2SO4) into the same test tube, drag the dropper towards it.
• You can see that a white precipitate is formed in the test tube.
• See the inference by clicking on the inference icon.
• To see the zoomed view of the test tube, click on it.
• To go back to the previous screen, click on the ‘Back’ button.
• Drag the test tube towards the beaker to decant the upper solution into it.
• To pour dilute HCl into the test tube containing the white precipitate, drag the dropper towards it.
• After shaking, you can view the zoomed view of the test tube by clicking on it.
• To go back to the previous screen, click on the 'Back' button.
• You can see the inference by clicking on the inference icon.
• You can click the ‘Reset’ button to redo the experiment.

Note: Click on the ‘HELP’ button to see the instructions.

Observation:

• A white precipitate appears that is insoluble in dilute HCl.

• When sodium sulphate chemically reacts with barium chloride in the form of their aqueous solutions, white precipitate of barium sulphate appears. This confirms the presence of sulphate (SO42-) ions.

• It is a double displacement reaction in which sulphate ions are displaced by chloride ions and chloride ions are displaced by sulphate ions.

 Precautions:

1. Use the chemicals judiciously.
2. Keep the mouth of the test tube away from your face and also from other classmates.
3. Handle the acids and alkali carefully.

So, try it out and “Have a safe lab!”

When barium chloride combines with sodium sulphate in the form of their aqueous solutions, a white precipitate of barium sulphate is formed which is insoluble in water. The reaction also creates sodium chloride, which remains dissolved in water and so cannot be seen. Here, the products formed are entirely different from the reactants in chemical composition and chemical properties. So this reaction is a chemical change.

This video explains the chemical change occurs during the reaction between sodium sulphate and barium chloride.

What do you observe when, barium chloride solution is mixed with sodium sulphate solution ?

\[\ce{\underset{\text{(aq.)}}{BaCl2} +\underset{\text{(aq.)}}{Na2So4}->\underset{\text{(ppt.)}}{BaSO4}+\underset{\text{(aq.)}}{2NaCl}}\]

We will observe that a white insoluble solid (precipitate) of barium sulphate is formed along with a solution of sodium chloride. Wait for ten minutes to complete the reaction and the solid formed to settle down.Weigh the content again and note the reading.We will observe that,total mass of the apparatus + reactants = total mass of apparatus + products

Hence the law of conservation of mass is verified.

Concept: Laws of Chemical Combination - Law of Conservation of Mass
