Question

how will you prove expirementally the law of conservation of mass?​

Answer 1

Take copper sulphate solution and dissolve it in water in a conical flask. Put cork on the mouth of the flask so that reactants and products do not spill out of flask. The mass of flask and its contents remain the same before as well as after the reaction that proves the law of conservation of mass.

The mass of flask and its contents remain the same before as well as after the reaction that proves the law of conservation of mass.

Mass can neither be created nor be destroyed. It can be demonstrated using a precipitation reaction between BaCl2 (aq) and Na2SO4(aq). According to the law of conservation of mass, Mass of reactants (barium chloride + sodium sulphate) = Mass of products (barium sulphate+ sodium chloride
