Red phosphorus is an allotrope of phosphorus. It is an amorphous polymeric red solid that is stable in air. ... It was discovered in 1847 by Anton von Schrötter. [1]
Phosphorus is a chemical element with the symbol P and the atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth.
This step was not necessary, as later scientists discovered that fresh urine yielded the same amount of phosphorus). [6] Boil urine to reduce it to a thick syrup. Heat until a red oil distills up from it, and draw that off. Allow the remainder to cool, where it consists of a black spongy upper part and a salty lower part.
Violet phosphorus (right) by a sample of red phosphorus (left) Hitorff's phosphorus structure. Monoclinic phosphorus, violet phosphorus, or Hittorf's metallic phosphorus is a crystalline form of the amorphous red phosphorus. [15] [16] In 1865, Johann Wilhelm Hittorf heated red phosphorus in a sealed tube at 530 °C. The upper part of the tube ...
Joseph Jacob Goldmark (15 August 1819 – 18 April 1881) was a Hungarian American physician and chemist, credited with the discovery of red phosphorus. [ 1 ] Life and career
People exposed to white phosphorus can suffer severe and sometimes deadly bone-deep burns. It can cause organs to shut down, and burns on just 10% of the body can be fatal, HRW said.
The major innovation in its development was the use of red phosphorus, not on the head of the match but instead on a specially designed striking surface. Arthur Albright developed the industrial process for large-scale manufacture of red phosphorus after Schrötter's discoveries became known. By 1851, his company was producing the substance by ...
A third and new species of seadragon has been discovered. Named the ruby seadragon, it joins its two known counterparts, leafy and weedy, in a group characterized by seahorse-like bodies and ...
