What did Justus von Liebig discover?
He was the first person the invent a nitrogen-based fertilizer. Liebig also devised the Law of the Minimum. The law states that growth is dictated not by total nutrients available, but by the scarcest nutrient (the limiting factor). Liebig was one of the true forefathers of modern agriculture.
In what year did Justus von Liebig suggest that acids gave off bubbles of hydrogen when mixed with metals?
Liebig’s aphorism of 1843, that the measure of a country’s civilization lay in the amount of sulfuric acid it consumes every year, became widely known.
Why did Justus von Liebig?
Justus Freiherr von Liebig (12 May 1803 – 20 April 1873) was a German scientist who made major contributions to agricultural and biological chemistry, and is considered one of the principal founders of organic chemistry….

What did Liebig and Wohler discover?
The most significant result of Wöhler’s and Liebig’s collaboration was their discovery of certain stable groupings of atoms in organic compounds that retain their identity, even when those compounds are transformed into others.
What did Liebig do?
von Liebig is well known until today as inventor of “Liebig’s Beef Extract” and chemical fertilizer. Through his analytical research on ether and chloroform in the 1830s, he has made remarkable contributions relevant for the discovery and development of anaesthesia.
How did Justus von Liebig invent the mirror?
Liebig found a way to coat glass with a thin layer of metallic silver by depositing the metal directly by means of a chemical reaction. The silver nitrate was converted into a thin layer of metallic silver which adhered to the glass. Presto, a mirror was born!
Who discovered NPK?
2 Radio broadcast of the sordid story of Fritz Haber, the scientist who discovered the method for transforming atmospheric nitrogen into liquid nitrogen.
What did Justus von Liebig said in terms of maintaining soil fertility?
Through Liebig’s experimental work, he also established the famous “law of the minimum,” that states that plant growth is constrained by the least available nutrient in the soil.
Who invented mirror?
Justus von Liebig
The invention of the silvered-glass mirror is credited to German chemist Justus von Liebig in 1835. His wet deposition process involved the deposition of a thin layer of metallic silver onto glass through the chemical reduction of silver nitrate.
What did Wohler discover?
Friedrich Wöhler was the first to synthesize an organic compound from an inorganic substance. In 1828, he synthesized urea by slowly evaporating a water solution of ammonium cyanate, which he had prepared by adding silver cyanate to ammonium chloride.
What was significant about the experiment done by Friedrich Wohler in 1827?
In 1828 Wöhler was the first to isolate the element beryllium in pure metallic form (also independently isolated by Antoine Bussy). In the same year, he became the first to isolate the element yttrium in pure metallic form.
