1.	Draw the digarm to show the experimental setup for the law of conservation of mass.
Answer» Procedure: • Prepare 5% solution of each: Sodium sulphate and BARIUM chloride. • Take little amount of sodium sulphate in a CONICAL flask and a little solution of barium chloride in an ignition tube. • Hang the ignition tube in the conical flask as shown in the figure below. • Put CORK on the flask. Weigh the flask . • Now, mix well the two solutions. • Weigh the flask once again. Observation : • Chemical REACTION is observed. • Weight of the flask remains unchanged before and after the reaction Conclusion : • Total mass of the products = Total mass of the reactants. Hence, Law of conservation of mass is proved.

Procedure:

• Prepare 5% solution of each: Sodium sulphate and BARIUM chloride.

• Take little amount of sodium sulphate in a CONICAL flask and a little solution of barium chloride in an ignition tube.

• Hang the ignition tube in the conical flask as shown in the figure below.

• Put CORK on the flask. Weigh the flask .

• Now, mix well the two solutions.

• Weigh the flask once again.

Observation :

• Chemical REACTION is observed.

• Weight of the flask remains unchanged before and after the reaction

Conclusion :

• Total mass of the products = Total mass of the reactants.

Hence, Law of conservation of mass is proved.
