Is Liebig known as the father of chemistry?

"The father of modern chemistry" refers to the famous French chemist Lavoisier (1743-1794). After repeated experiments, he put forward the theory that combustion is an oxidation and reduction reaction, which effectively refuted the erroneous view that the substance burns because the substance contains phlogiston, and thus put chemistry as a science on the right track. As a result, he earned the reputation of "the father of modern chemistry".

The Father of Modern Chemistry - Lavoisier Lavoisier was a French chemist. He was born in Paris on August 26, 1743 and died in Paris on May 8, 1794. He received a bachelor's degree in law in 1763.

Yes, it's Liebig in high school chemistry textbooks.

Justus von Liebig (born 12 May 1803 in Darmstadt, Germany, died 18 April 1873 in Munich, Germany) was a German chemist whose most important contributions were in agriculture and biochemistry, and he founded organic chemistry. Therefore, he is called the "father of chemistry". As a university professor, he invented the modern laboratory-oriented teaching method, and for this innovation, he is known as one of the greatest chemistry educators in history.

He discovered the importance of nitrogen for plant nutrition, which is why he is also known as the "father of the fertilizer industry".

In 1824, he completed the research of a series of thunderic acid compounds. At this time, Weller was working on cyanide. Their separate articles were published at the same time in a journal edited by Gelussac, who pointed out that the two different classes of compounds had the same molecular formula.

This is the first time that chemists have discovered that different compounds have the same molecular formula, and the term "isomer" was born. At the same time, he also took this opportunity to become a lifelong close friend with Weller. From that year onwards he began teaching at a university in a small town called Giessen, pioneering the establishment of a general laboratory for students.

Liebig devoted himself to organic chemistry with great enthusiasm.

The true "father of organic chemistry."

It was a good friend of Weller, the German chemist Liebig.

Liebig studied in France.

He became independent from Wühler in 1823.

A cyanic acid was separated.

The chemist Gelussack believed that the molecular formula of the two substances was the same. And so they pioneered isomers.

and led to the creation of structural chemistry.

In Germany, Liebig studied chemistry with Wüller. They mainly work on organic fertilizers, and because of their excellent work, Germany has become a world center for fertilizer research in the field of organic chemistry.

Liebig not only did his own research, but also covered the world.

Together with Wüller, he called for a group of young scholars to form a dynamic research community.

From 1824 onwards, Liebig taught at the University of Giessen. As a result, the University of Giessen became a chemistry center in Germany. Liebig opened a laboratory for students and was very popular. He is world-famous, making the otherwise unknown University of Giessen and the city of Giessen famous in Europe.

Wühler developed the doctrine of groups with Liebig. They believe that organic compounds are all based on stable groups, and that the groups are the unchanged part of a series of compounds, and can even replace each other or be replaced by simple substances.

Liebig also influenced the German chemist Kekule. Kekule, who originally studied architecture, switched to chemistry under the influence of Liebig, and achieved great success, proposing "affinity."

value" theory. Later, the theory of carbon tetravalent was emphasized, which laid the foundation for the theory of organic chemical structure.

Liebig was also the first to experiment with chemical fertilizers.

The people who came to fertilize the land, although they did not succeed, opened up a new path.

Liebig's greatest contribution was quantitative analysis in organic chemistry. The structure of the elements is deduced from the content of various elements, and the chemical formula is derived.

This pair of friends has contributed greatly to the history of scientific development.

Liebig Eustus von Liebig (born May 12, 1803 in Darmstadt, Germany, died April 18, 1873 in Munich, Germany) was a German chemist whose most important contributions were in agriculture and biochemistry, and he founded organic chemistry. Therefore, he is called the "father of organic chemistry". As a university professor, he invented the modern laboratory-oriented teaching method, and for this innovation, he is known as one of the greatest chemistry educators in history.

He discovered the importance of nitrogen for plant nutrition, which is why he is also known as the "father of the fertilizer industry".

Liebig, a German chemist, was born in Darmstadt.

As a young man he worked as an apprentice in a pharmacy. He graduated from the University of Erlangen with a doctorate in the form of thundermercury.

In classical chemistry, Liebig made contributions to both inorganic chemistry and organic chemistry, he discovered the isomer of isocyanic acid, improved the quantitative analysis method of carbon and hydrogen in organic matter, prepared chloroform, trichloroacetaldehyde, creatine, etc., and put forward the "organic root theory" and "homogeneity theory"; Together with Wühler, he discovered the "phenylacetyl group" and proposed the concept of a "compound group"; He created chemical instruments such as the "Liebig Ball" and was the first to establish a chemistry laboratory in a university.

In biochemistry and agricultural chemistry, Liebig studied the chemical principles of fermentation and spoilage, applied chemistry to agricultural production, and proposed the theory of mineral nutrition of plants. From the analysis of plant ash, it was found that salts containing potassium and phosphorus had a great impact on the development of agriculture.

Teach "farming".

One day, Liebig went to the fields on the outskirts of the city, bent down and carefully examined the crops and the soil. A peasant who was working in the fields looked at the scholar-like city man strangely and asked, "Sir, do you know how to grow crops?" ”

Well, I don't know much, and I just want to learn. "Libbig. He then asked, "Do you think this year's harvest will be good?" ”

This casual question touched the heart of the peasant, and he sighed worriedly and said: "How can we expect a good harvest when we grow crops year after year, and the land is getting poorer and poorer?" The land is about to be abandoned. ”

If you can add some nutrients to the land, won't the crops be abundant? Liebig muttered to himself, as if to the peasants.

Sir, you don't understand. Our crops have been farming like this for generations, and your words will make a joke. The farmer said with some amusement.

Leebig didn't care if he was making jokes.

What exactly is lacking in arable land? What do I need to know for crops to grow? Liebig asked himself.

In order to find out, Lieutenant began a large number of experiments. In his experiments, he found that nitrogen, phosphorus, and potassium are indispensable for plant growth.

The world's first chemical fertilizers were finally produced. However, when the fertilizer is soaked in rainwater, it seeps into the deep layers of the soil, but the plants do not absorb the nutrients, and the crops do not increase significantly.

So, they started a new exploration. This time, Liebig synthesized potassium and phosphate crystals into a fertilizer that is insoluble in water.

Finally, on a barren field, Liebig and his assistants mixed the white crystals with clay and rock salt, applied them to the soil, and planted crops. After a while, the farmers were amazed to find that the abandoned "barren land" had miraculously grown a green crop, and it grew stronger and stronger. In the blink of an eye, the harvest season has ushered in again.

The barren land "has a good harvest than the crops planted by the peasants in the good fields."

Since then, chemical fertilizer has become a treasure for farmers.
