What is londalt experiment

Answer 1

Antoine Lavoisier, a French chemist, stated the law of conservation of mass in 1785.

Statement:

"In any chemical reaction, the initial weights of reactants is equal to the final weights of products"OR
"Mass is neither created nor destroyed during a chemical reaction but it only changes from one form to another"
Landolt Experiment:
H. Landolt was German Chemist. He proved the law of conservation of mass by using an H-shaped glass tube. he filled silver nitrate in limb A and hydrochloric acid in limb B. The tube was sealed and weighed before the chemical reaction. The reactants were mixed by inverting and shaking the tube. A white precipitate of silver chloride was formed along with nitric acid. The tube was weighed again. He found that there was no change in weight during the reaction
