Give one experiment involving a chemical reaction to prove that the law of mass is true
Dear student,
- When the solution of X is mixed with solution of Y, the chemical reaction will take place. If the solution of X and Y do not mix, no chemical reaction will occur. For example when copper sulphate reacts with sodium chloride to form copper chloride and sodium sulphate.
- Yes! Chemical reaction will take place after the mixing of X and Y solutions. For example when barium chloride reacts with sodium sulphate, it forms sodium chloride and barium sulphate.
- We put the cork on the mouth of conical flask so that no mass lose occur during the chemical reaction.
- The mass of flask and content will remain same before and after the chemical reaction because the flask is closed by cork so no mass lose occurs.
- Hence it proves the law of conservation of mass during the chemical reactions.
