Question

How can you verify conservation law using barium chloride and sodium sulphate solution?

Answer 1

Answer:

bacl2+na2so4=2nacl+baso4

Explanation:

first write an balanced chemical equation. then calculate the total mass of reactant and product. both of their masses will be equal .

hence the law is proved

Answer 2

Answer:

(barium chloride+sodium sulphate)=mass of products (barium sulphate+sodium chloride)

Explanation:

Mass can neither be created nor destroyed in a chemical reaction.

take Barium chloride solution in a conical flask and sodium sulphate in a small test tube.keep the test tube inside the conical flask.now weigh the flask using a weighng balance and note the reading. tilt and swirl the flask so that sodium sulphate solution in the test tube spills and mix with barium chloride in the flask.this forms a white coloured precipitate of barium sulphate(BaSO4) and an aqueous solution of Sodium chloride(NaCl).Now weigh the flask again.there will be no Change in the weight before and after the reaction.

therefore,we verified..
