Which of the following metals, known by the name Jasada, was known to ...
Jasada is an ancient term used in India to refer to the metal zinc. This metal was known to the Indians in the 14th century, long before it was isolated and identified by the European chemist Andreas Marggraf in 1750.
Explanation:
- Zinc is a chemical element with the symbol Zn and atomic number 30. It is a bluish-white metal that is commonly used in alloys and for galvanizing iron and steel to prevent corrosion.
- The term Jasada was used in ancient Indian texts to refer to a type of metal that was used in medicinal preparations. This metal was later identified as zinc.
- The Indians were aware of the properties and uses of zinc long before it was isolated and identified as an element. They used zinc oxide as a cosmetic, and zinc metal was used in the manufacture of brass and other alloys.
- Andreas Marggraf, a German chemist, is credited with the discovery of zinc as an element in 1746. However, it is now known that zinc was used in India long before this time.
- The ancient Indians also developed a process for the extraction of zinc from its ores, which involved heating the ore with charcoal in a closed vessel. This process was known as the "rasayana" method and was described in detail in ancient Indian texts.
In conclusion, the metal known as Jasada in ancient India was zinc, which was known to the Indians long before it was isolated and identified by European chemists.
