Carl Wilhelm Scheele (1742 - 1786)

Lets take a quick look at who we've got on our list of great scientists today:

Name: Carl Wilhelm Scheele
DOB: 9th/Dec/1742
Died: 21st/May/1786
Discovery: Manganese dioxide Analysis (let to Chlorine and Barite discoveries.)

 Carl Wilhelm Scheele to history was a Sweedish Chemist who was born in Stralsund in the year 1742 and died in Koping on the 21st day of May in the year 1786.
Carl was basically interested in the various themes of pure chemistry, especially because of his 28 years of close friendship with Bergman.

Carl Wilhelm Scheele was called in 1775 as a member of the Science Academy of Stockholm (oh! that's a big Academy. I am also dreaming of one as a scientist too). In the same year, Frederic the great tried to pull him to continue his studies at any University in London or better still,close up at Berlin but refused and decided to settle down with his own pharmacy at Koping, where most of his original works was accomplished.
In 1774, Carl analyzed the Manganese oxide which lead the way through to the discovery of Chlorine and Barite and some other descriptions of Manganese compounds.

Chlorine.

A common sense will flash us back to NaCl when we talk about Chlorine. But we did rather say Chlorine ia a heavy yellow irritating toxic gas  belonging to the Halogen family. It is used to purify water and also serve as a bleaching agent and a disinfectant.
It is the chemical element with atomic number 17 and Cl as symbol.

Barite.

Barite isn't a common element to common science students in this part of the world but we all learnt that barite is an heavy spar,white,colourless,light blue,light yellow or light red in colour. It can be used in the medical arena as an inicator or as a paint pigment or lubricant when added to other compounds in the chemical industries.
