Question

Ramesh performed an experiment to prove the law of conservation of mass.He took salts of Barium chloride and Sodium sulphate in separate testtubes and then mixed the two.He did not get the desired results. Why could Ramesh not conclude?What was the expected conclusion of the experiment?​

Answer 1

Ramesh was supposed to take barium chloride and sodium sulphate in its solution form as these compounds react only on being mixed in solution form. If done correctly he would have got Barium sulphate, a white precipitate (insoluble solid) and sodium chloride, a solution.
