Book review

French chemist Joseph Louis Proust (1754-1826), who worked in Spain, held the opposite view. Through careful analysis Proust in 1799, demonstrated, for example, copper carbonate characterized by a specific weight ratio of copper, carbon and oxygen, regardless of which way the salt obtained in the laboratory or in isolated manner from natural sources. The compound always contains 5.3 parts of copper, 4 parts oxygen and one part carbon. Moreover, Proust found that persistence ratios of components is observed in a number of other compounds. He formulated the general rule that all compounds contain elements in strictly defined proportions (but not in any combination), regardless of the conditions for obtaining these compounds. This rule is called the law of constant composition, or sometimes the law of Proust. (Proust also showed that Berthollet, trying to prove that the composition of certain compounds varies depending on the production method, came to erroneous conclusions because of the inaccuracy of analyzes and the use of insufficiently pure starting compounds.)
