A few days ago we were talking about the element number 30 of the periodic table: zinc.
Today we want to talk to you about Andreas Sigismund Marggraf. He was a German chemist from Berlin and a pioneer of analytical chemistry.
Lived between 1709 and 1782 he is the son of the court pharmacist who taught the young Andreas pharmacology and chemistry. Later Andreas was, as a student at the School of Chemistry, a pupil of Professor Caspar Neumann, director of the department of experimental chemistry (pharmacy) at the Medical-Surgical College in Berlin. Neumann introduced Marggraf to the phlogistic theory, which was to characterize his life. To deepen his knowledge, Marggraf studied chemistry and physics in Strasbourg, medicine in Halle and metallurgy in Freiberg (Saxony).
Back in Berlin, Marggraf worked in his father's "At the Golden Bear" pharmacy until 1738, when he became a salaried member of the Berlin Academy of Sciences. From 1754 he was able to concentrate totally on his chemical research, since a laboratory and a service apartment were placed at his disposal by the Academy.
Maargraf stayed away from the controversy over chemical theory of the time and devoted himself to laboratory research, a behavior which, together with his successes in finding him, earned him numerous awards.
He was the last significant chemist of the "phlogistic" era.
His scientific contributions:
- Improvement of the method of extraction of phosphorus by distillation from vaporized urine, with chlorate of lead, sand and coal (1743)
- Production of potassium cyanide and description of its properties in the treatment of metal salts (1745)
- Zinc extraction through the reduction of "cadmiums" with coal dust (1746)
- Discovery of the presence of sugar in local plants, particularly in beets (1747)
- Introduction of the microscope as a tool for chemical research, which he used to identify sugar crystals (from 1747)
- Obtaining formic acid (1749)
- Distinction of formic acid from acetic acid through the reduction of mercury oxide with formic acid
- Distinction between sodium and potassium through the color of the flame (1758)
This giveaway is linked to the zinc giveaway. Whoever commented on that article will participate in the extraction of 100 NFT of zinc and 140 NFT of Andreas Sigismund Marggraf. He is the third celebrity in our series.
In a single article we have organized a double distribution. In order not to give little importance to our celebrity we have decided to dedicate a separate article. The comments of this article will allow you to participate in the extraction of zinc and Marggraf.
Those who comment on both articles will be admitted with a single ticket.
Let's remember the giveaway rules:
For the assignment of both, an extraction will be made among all those who comment the two articlea with their WAX address by January 17th at 16:00 CEST (a user an address).
The first NFT concerns the new element, zinc, with a max supply of 200. 50% of the supply is assigned to the giveaway and the first 100 users resulting from the extraction will be awarded.
The second NFT is about the third celebrity of chemical characters. We do not reveal the name and history at the moment. The max supply of celebrities is 149. The last 140 results from the draw will be awarded.
There will most likely be people who will receive a double NFT - virtue lies somewhere in between.
If, on the other hand, there were more than 250 comments (the exit polls do not provide it), we will invent something to also find a reward for those who were excluded from the double giveaway.
The Periodic Table NFT project
The Periodic Table NFT project aims to raise awareness of chemical elements in a modern key, basing the approach on blockchain and Non Fungible Token.
Day after day it will be possible to know the single elements that make up the table, to collect curiosities about each of them and about the table in general.
We are working to be able to learn, in a playful way, also what happens by combining the various elements.
The whole project is based on the collection of NFTs that can be bought on the site https://wax.atomichub.io/market?collection_name=periodicelem&order=desc&sort=created&symbol=WAX or by participating in simple giveaways published on publish0x.
- H2O - Water (max supply 37)
- NaCl - Salt (max supply 64)
- CaC2 - Calcium carbide (max supply 46)
- KMnO4 - Potassium permanganate (max supply 57)
- Lavoisier (max supply 149)
- Glauber (max supply 149)
- Marggraf (max supply 149)
