Law of conservation of mass was proposed by

The father of modern chemistry “Lavoisier was proposed the law of conservation of mass in chemical reactions”. It means there is no change in the sum of the mass of all reactants and products during the reaction.

The father of modern chemistry, Antoine Lavoisier, is credited with proposing the Law of Conservation of Mass in the late 18th century. This fundamental principle states that during a chemical reaction, the total mass of the reactants before the reaction is equal to the total mass of the products after the reaction. In other words, matter is neither created nor destroyed in the course of a chemical reaction.

This law was groundbreaking because it challenged earlier theories that suggested mass could be lost or gained during chemical processes. Lavoisier’s meticulous experiments, including the study of combustion reactions, demonstrated that the mass of substances involved in reactions remained constant. His work laid the foundation for modern chemistry, providing a scientific basis for understanding chemical reactions, stoichiometry, and the conservation of matter in closed systems.

In practical terms, this means that in any chemical reaction, whether it’s a simple reaction like the rusting of iron or more complex reactions in industrial processes, the mass of the starting materials (reactants) will always be equal to the mass of the end products, assuming no material is lost to the surroundings. This concept is crucial in both laboratory experiments and real-world applications, ensuring that chemical processes are balanced and predictable.
