This law, also known as Proust's Law, states that a chemical compound always contains exactly the same proportion of elements by mass. Joseph Proust argued that chemical compounds are composed of elements in fixed ratios by mass. According to his experiments, a compound like copper carbonate, regardless of its source, always consisted of the same proportion of copper, carbon, and oxygen. This consistency supported his view that chemical reactions produce compounds with definite and unchanging compositions. Claude Louis Berthollet, on the other hand, believed in the concept of variable composition. He argued that the proportions of elements in compounds could vary depending on the conditions under which they were formed. Berthollet's observations, especially those related to alloys and certain solutions, suggested that elements could combine in varying ratios, leading him to challenge Proust's assertion of fixed proportions. The debate between Proust and Berthollet lasted for several years and involved numerous experiments and theoretical arguments. Ultimately, Proust's views were vindicated through consistent experimental evidence. The discovery of the law of multiple proportions by John Dalton, which further elaborated on the idea that elements combine in specific ratios to form different compounds, provided additional support to Proust's law. Proust's law of definite proportions became a foundational principle in chemistry, reinforcing the understanding that compounds have consistent and specific elemental compositions. This principle helped pave the way for the development of modern chemical formulas and stoichiometry, and it underscored the importance of precise measurement and analysis in chemical research. Thus, while Berthollet's ideas contributed to the broader understanding of chemical reactivity and mixture compositions, it was Proust's assertion of definite proportions that proved to be correct for true chemical compounds. This resolution was a significant step forward in the field of chemistry, confirming the predictability and consistency of chemical reactions and compositions.

This theory, initially proposed by the German chemist Becher, was regarded as a sacred doctrine at the time. Becher argued that matter was composed of water and three kinds of earth. Another German chemist, Stahl, named the oily earth "phlogiston." He theorized that when a person died, phlogiston would escape, equating it with the soul. Consequently, refuting the phlogiston theory was seen as an act of sacrilege. The core of the phlogiston theory was the belief that the presence of phlogiston in a substance was what caused it to burn. However, Lavoisier, through his experiments with mercuric oxide, proved that it was oxygen, not phlogiston, that facilitated combustion. When metals like tin or mercury are burned, their mass actually increases, directly contradicting the phlogiston theory. This discovery was groundbreaking at the time. Moreover, Lavoisier demonstrated through water decomposition experiments that if steam is prevented from escaping and heated, the amount of water does not decrease. This proved that matter is neither naturally created nor destroyed and that mass is always conserved. Because of this, Lavoisier is often called the father of modern chemistry for advocating the law of conservation of mass. There are some who claim that the Russian scientist Lomonosov discovered this law first. However, since France's influence was much stronger than Russia's at the time, Lomonosov's claims received less recognition. This situation is similar to Gutenberg's metal type being more famous than Korea's Jikji, which was invented much earlier but is less well-known.
