Biography of Chemist - Antoine-Laurent Lavoisier
Ever heard of his name? If you love chemistry and are studying it now, you must have heard of Antoine-Laurent Lavoisier.
Yes, he is one of the famous chemists who formulated the law of conservation of the masses. The law that he formulated is must you must learn, especially if you want to understand about chemical stoichiometry.
Many other interesting facts from Antoin-Laurent Lavoisier are unknown by many people. For that, read this article to the end so you know more about the famous chemist Antoine - Laurent Lavoisier.
Lavoisier was born from a family in law. His father was a famous and very successful lawyer in the city of Paris, where Lavoisier was born on August 26, 1743. His mother was a successful butcher shop owner. But his mother died when Lavoisier was 5 years old.
His family wished he could continue his father's legal profession by becoming a lawyer.
As a teenager, Lavoisier studied at one of the prestigious universities in Paris, named College des-Quatre Nation. In this college, he studied many general subjects, including natural science.
He was very interested in natural science, especially chemistry and physics. However, his father said that he had to study law to become a lawyer like himself.
Therefore, when Lavoisier was 18 years old he entered a university to study law. A few years later, he graduated and obtained a law degree. In 1764 Lavoisier obtained permission to open his own law firm's office.
This fact is quite surprising, is not it! How a law Bachelor can find and formulate laws in the field of chemistry. Let's read on!
After obtaining a law degree, Lavoisier then worked as a public servant in the French administrative office. His job in government did not give him enough time to study natural science.
Despite being a bachelor in law, Lavoisier was unable to leave his interest in natural science, especially chemistry. He never even practiced the law he had ever studied. While studying law, he also studied geology from a teacher named Etienne Condillac and attended many lectures on natural science.
He conducts and publishes many kinds of research in chemistry and geology. One is a paper on the chemical and physical properties of gypsum (calcium sulfate hydrate).
In 1766, he was awarded a gold medal by the French king for making an essay on how to improve street lighting in Paris.
Then in 1769 Lavoisier was appointed a junior member of the French natural sciences Academy, The Academy is home to the most prestigious chemists and physicists in France.
In this academy, he then conducted many kinds of research in the field of chemistry.
Lavoisier is married to a woman named Jawues Paulze, who is the daughter of Farmer's General. Farmer's General is a private company in charge of collecting taxes from the public and setting tariffs. Taxes collected are then submitted to the government.
Jawues Paulze is a very influential woman against Lavoisier's scientific career. After marrying her, Lavoisier and his wife moved to Arsenal, England. Here he built a laboratory to undertake various research in chemistry.
Jawues Paulze served as the assistant in translating the results of Lavoisier's research into French, laboratory assistant while conducting research and helping draw diagrams for the purposes of the research report.
Discovery in the Field of Science
The Role of Oxygen in Combustion
In the phlogiston theory, chemists predict that when a combustion reaction happens, it is released a particle called a phlogiston into the air.
But Lavoisier finally proves that this theory is not true. Lavoisier says that there is no such thing as a phlogiston when the combustion reaction takes place.
The combustion reaction is a reaction between chemicals contained in a material burned with oxygen in the air. Lavoisier's statement proved true and still used today.
Lavoisier is also the first person to name the oxygen gas under the name "oxygen" which means to produce acid.
The Law of Conservation of Mass
In the law of mass conservation, Lavoisier concludes that the amount/mass of the reacting agent will be equal to the amount/mass of the substance formed after the reaction.
This means that when a reaction occurs, no atoms are lost or created. It is therefore concluded that the mass of matter is eternal.
This law we can prove by way of reacting substances in a closed space.
Water Is Not Element
Many chemists believe that water is an element. Lavoisier, however, said that the water is a combination of two types of gases: oxygen and nitrogen. Although the constituent elements he mentions are incorrect (water composed of oxygen and hydrogen), he succeeds in changing people's view that water is not an element.
Dead
Lavoisier died very tragically. After the French Revolution, he and 7 other Farmer's General members were alleged to have made a mistake and were eventually arrested.
They were put on trial very quickly and then executed dead. Many people deplore this trial, as Lavoisier's contribution to science is enormous. He died in Paris on 8 May 1794, when he was 50 years old.
