To Verify Law of Conservation of Mass in a Chemical Reaction
Mass is an isolated system. The law of conservation of mass states that the mass can neither be created nor destroyed in a chemical reaction. There is just a rearrangement in the atoms of substances for the formation of compounds. Therefore, the mass of the total system remains constant at any interval of time. This implies that the total masses of reactants is equal to the sum of masses of products and the masses of unreacted reactants. The law of conservation of mass is also termed as the principle of mass conservation.
Mass of the total enclosed system at the beginning of the reaction is equivalent to the mass at the termination of the reaction.
Mass reactants = Mass products
Experiment to verify the law of conservation of mass
The following experiment can be conducted to verify the law of conservation of mass:
Things required to perform the experiment:
Barium chloride (BaCl2.2H20),
Sodium sulphate (Na2SO4.10H2O),
Two beakers of 100 and 150 ml respectively.
Physical balance
Two watch glasses
Spring balance (0-500 g),
Polythene bag
Distilled water
A glass rod.
