Scheele, named after the Swedish chemist Carl Wilhelm Scheele, refers to a variety of terms associated with his significant contributions to the field of chemistry. In its most common usage, Scheele refers to Scheele's green, a vivid green pigment known scientifically as copper arsenite. Scheele's green was first synthesized by Scheele in the late 18th century and became widely used in the manufacturing industry as a vibrant coloring agent. However, it was later discovered to be highly poisonous due to its arsenic content, leading to its subsequent ban and replacement by safer alternatives.
Another use of the term Scheele pertains to Scheele's acid, the common name for chlorate(I) or hypochlorous acid. Although it was initially synthesized by Scheele, the acid's unstable nature and susceptibility to spontaneous decomposition made it more recognized as a theoretical compound rather than one with practical applications.
Furthermore, Scheele may also refer to the Scheele apparatus, an experimental set-up invented by Scheele that allowed for the production of various gases. This apparatus comprises specific glass tubes and vessels, including retorts, condensers, and gas collectors, facilitating the isolation and examination of gaseous substances.
Overall, the term Scheele signifies the name and contributions of Carl Wilhelm Scheele, encompassing his discoveries in various areas of chemistry, such as pigments, acids, and experimental apparatuses.
