| Antoine Lavoisier [Antoine-Laurent de Lavoisier] was a French scientist who lived from August 26, 1743 to May 8, 1794. Lavoisier, known as the "Father of Modern Chemistry," was a French aristocrat who played an important role in the history of chemistry and biology. |
Personal Details of Antoine Lavoisier (Father of Chemistry)
Important details of Antoine Lavoisier (Father of Chemistry) is tabulated below:
Chemistry is the study of matter, which is defined as everything having mass and occupied space, and the changes that it may undergo when subjected to diverse environments and situations. Chemistry is not only used in scientific investigations but it is also used in everyday life. It represents the advancement of civilization and humanity. The everyday task involves a certain amount of chemistry and is vital in numerous areas, including health, agriculture, and engineering.

The Chemistry of Pneumatics
As a student, Lavoisier studied chemistry, which was not known for its conceptual clarity or theoretical rigor.
- Although chemical texts provided a wealth of information on the substances investigated by chemists, there was no agreement on the precise composition of chemical elements or on explanations for changes in composition.
- Many natural philosophers continued to see the four elements of Greek natural philosophy—earth, air, fire, and water—as the essential constituents of all matter.
- Chemists such as Lavoisier concentrated their efforts on examining "mixes" (i.e., compounds), such as the salts created when acids and alkalis interact.
- Stephen Hales, an English priest, and natural philosopher, established in the 1720s that atmospheric air loses its "spring" (i.e., elasticity) when it becomes "fixed" in solids and liquids.
- Perhaps the air was merely a vapor like steam, and its spring, rather than being a fundamental quality of the element, was formed by heat, according to Hales.
- Hales investigations were a significant initial step in the experimental study of particular air or gases, which became known as pneumatic chemistry.

What were Antoine Lavoisier's Contributions and Achievements?
Antoine Lavoisier discovered that oxygen was an important ingredient in combustion and named the element after himself. He invented the present method of identifying chemical compounds and is known as the "Father of Modern Chemistry" because of his emphasis on rigorous testing.

Who was Marie-Anne Lavoisier?
In 1771, Marie-Anne Paulze married Antoine Lavoisier. She helped Antoine with his experiments. She drew the illustrations for many of his works and translated them from English for him because he didn't speak them.

Combustion Theory
When elements interact with anything in the air, they gain weight, as Antoine Lavoisier observed. In 1774, Joseph Priestley, a British chemist, extracted a component of air by heating mercury calx (oxide). He believed it was pure air since it facilitated respiration and combustion so well. Priestly invented the term "dephlogisticated air," claiming that its unique properties were due to a lack of phlogiston.
- Lavoisier repeated the experiment with mercury and other metal oxides after informing him of his discovery.
- He realized that air contained two components: one that connected with the metal and allowed for breathing, and one that did not.
- In 1778, Lavoisier proposed a new theory of combustion, describing it as the interaction of metal or organic material with the "eminently respirable" component of common air.
- The next year, he coined the name "oxygen," which is derived from Greek terms that mean "acid generator."
- Lavoisier's discovery of the function of oxygen in combustion is considered one of his most significant accomplishments.

Sulphur
- In 1772, Antoine Lavoisier and his chemists placed a diamond in a jar and used a huge magnifying glass to focus the sun's rays on it.
- The diamond was engulfed by fire and burned away. According to Lavoisier, when diamonds or charcoal are burnt, neither produces water nor emits the same amount of carbon dioxide per gram.
- As a result, he determined that diamond is a crystalline form of carbon, coining the term "chemical allotropy."
- In 1787, Lavoisier proposed that silica was an oxide of a fundamental chemical element, thereby predicting the discovery of silicon.

The First Modern Chemistry Textbook
- Antoine Lavoisier's most famous work, Traité élémentaire de chimie, was published in 1789.
- The results supported Lavoisier's oxygen hypothesis of combustion while ruling out the presence of phlogiston.
- It defines an element as a single material that cannot be chemically broken down and serves as the basis for all chemical compounds.
- It included an element list, which served as the foundation for the present element list.
- The results were backed by Lavoisier's oxygen combustion theory and ruled out the presence of phlogiston.
- It defines an element as a single material that cannot be chemically broken down and serves as the basis for all chemical compounds.
- It contained an element list, which served as the basis for today's element list.

The Law of Mass Conservation
Antoine Lavoisier developed the Law of Conservation of Mass in 1789 after discovering that mass is never generated or destroyed in chemical interactions. According to the Law of Conservation of Mass, the matter may be transformed from one form to another, mixtures can be separated or created, and pure substances can be dissolved, but the overall amount of mass stays constant. The Law of Conservation of Mass may be used to solve for unknown masses, such as the quantity of gas consumed or created during a reaction, and is useful for a variety of computations.
As a result, atoms are not changed into other elements during chemical reactions in the ordinary world of Earth, from the summit of the tallest mountain to the depths of the deepest ocean. Living creatures are composed mostly of six elements-
- Oxygen
- Carbon
- Calcium
- Nitrogen
- Phosphorus
- Hydrogen

Water
- Antoine Lavoisier named the gas that Henry Cavendish identified as a new element in 1766 "hydrogen" in 1783.
- Cavendish gave the combustible material the name air.
- In 1783, Lavoisier performed a series of tests on water composition with the help of French mathematician Pierre Simon de Laplace.
- The two used hydrogen and oxygen jets in a bell jar over mercury to create "water in a highly pure condition."
- Water was demonstrated to be a combination of two gases, hydrogen, and oxygen, rather than an element, based on quantitative evidence.
- Everyone has considered water to be an element since Aristotle included it in his four elements over 2,000 years ago, and this was an important finding.
- Water's interpretation as a compound explained the reduction of oxides by inflammable air (hydrogen) created by dissolving metals in acids.

Death and Philosophy
When the French Revolution occurred in 1789, Lavoisier, like many other philosophically-minded managers, saw it as an opportunity to rationalize and improve the nation's politics and economy by reducing oxides of inflammable air (hydrogen) generated by dissolving metals in acids, and the inflammable air was explained by water's interpretation as a cause. On the other hand, upheavals swiftly shattered such faith, threatening the state's very survival. Lavoisier continued to counsel Revolutionary administrations on finance and other subjects, maybe overestimating science's authority and the force of reason. When popular fury erupted against individuals who possessed authority and enjoyed social benefits during the former administration, he and his wife did not move abroad.
- As the Revolution got more extreme and those in power were forced to govern by fear, Lavoisier continued to advocate that the Academy of Sciences should be spared.
- When this last-ditch attempt failed, he was instantly imprisoned alongside other members of the General Farm.
- The Republic's royalist past was being erased. In May 1794, Lavoisier, his father-in-law, and 26 other tax farmers were hanged.
- "It took them barely a second to remove that head, and a hundred years may not produce another like it," a contemporary, Joseph-Louis Lagrange, said, recognizing Lavoisier's scientific significance.
Who is the Father of Chemistry in India?
The Father of Chemistry in India is Acharya Prafulla Chandra Ray.
He was a chemist, educator, and industrialist par excellence, most known as the founding father of Bengal Chemicals & Pharmaceuticals, which was India's first pharmaceutical company. His works on nitrites and nitrates in inorganic chemistry made great strides in the science. He also advocated science education in the Indian subcontinent.
