Question

explain the process and precautions in verifying law of conversation of mass​

Answer 1

Answer:

Precaution: To initiate the chemical reaction tilt the flask efficiently so that barium chloride solution gets mixed with the sodium sulphate solution in the flask. The mass of both of the solution before reaction was found to be same after the product is formed. So, this verifies the law of conservation of mass.

Answer 2

$\Large\bf\underline\red{Answer}$

$Explanation:$ The sodium sulphate solution is to be taken 5ml in a conical flask. Add 5ml of barium chloride in a 10 ml test tube. The mass of both of the solution before reaction was found to be same after the product is formed. So, this verifies the law of conservation of mass.
