lavoisier

With the rapid development of Chemistry and the discovery of new elements, it was necessary to develop a simple way to study and remember the numerous properties of the elements and their compounds. This gave rise to the necessity of classification of the elements into various groups having similar..

Origin of Organic Chemistry Carbon compounds are of two types: inorganic and organic. The compounds that have a mineral origin fall under the category of inorganic compounds. The compounds having plant or animal origin are classified as organic compounds. Lavoisier showed tha..

Sulphur was initially called brimstone Free sulphur 'gandhaka' was known in India 3000 years ago It was used in fumigation, medicines and bleaching by Aryans, Greeks and Romans In 1777, Lavoisier was the first to recognize the basic nature of sulphur Sulphur is essential to ..

Introduction - Origin of Organic Chemistry Carbon compounds are of two types: inorganic and organic. The compounds that have a mineral origin fall under the category of inorganic compounds. The compounds having plant or animal origin are classified as organic compounds. Lavoisier showed t..

Discovery of Nitric Acid - Johann Glauber (1604-1668) prepared nitric acid by heating nitre with concentrated sulphuric acid and then condensing the vapour. While Henry Cavendish determined the composition of nitric acid, Lavoisier proved that oxygen is present in nitric acid. Some Basic ..

. Hence that air was called "Dephlogisticated Air". Antonie Lavoisier, a French chemist, gave oxygen its present name. 'Oxygene' in French means "Acid producer", for, during Lavoisier's time all known acids contained oxygen. The name was modified to Oxygen in English. In fact th..

This law was put forth by the French chemist A. Lavoisier (1774). It states that in 'any chemical reaction, the total mass of the system before and after the reaction is the same although its matter can undergo a physical change'. If 'a' grams of A and 'b' grams of B react to give 'c' gr..
