Nikolaus Wolfgang Fischer

Nikolaus Wolfgang Fischer is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Nikolaus Wolfgang Fischer rather than just read about it. In short: Nikolaus Wolfgang Fischer (15 January 1782 – 19 August 1850) was a German Jewish chemist. He first synthesized the Potassium cobaltinitritelater used as Aureolin pigment.

Key takeaways

Nikolaus Wolfgang Fischer belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Nikolaus Wolfgang Fischer to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Nikolaus Wolfgang Fischer from memory before moving on to harder problems.

Reference excerpt

Nikolaus Wolfgang Fischer (15 January 1782 – 19 August 1850) was a German Jewish chemist. He first synthesized the Potassium cobaltinitritelater used as Aureolin pigment. Fischer was raised in a Jewish family. He was reported to have practiced medicine in Erfurt and studied at the University of Vienna, Charles University, University of Breslau, and the Humboldt University of Berlin. In 1813, he became an assistant professor at the University of Breslau, and then became a professor and worked as the chemistry department's first chair. He held this position until his death. In 1815, Fischer converted to Christianity and was an ardent supporter of evangelizing.

Career Fischer published about sixty works in German journals. He reported on the triple salt K3 Co(NO2)6, also known as "Fischer's salt" and used it to separate nickel from cobalt. Fischer also observed the semipermeability of animal bladders in solutions, which he wrote about in "Über die Eigenschaft der thierischen Blase, Flüssigkeiten durch sich hindurch zu lassen." He also took great interest in electrochemical phenomena. Some of his works include articles in:

Journal für Chemie und Physik Schweigger's Annalen für Chemie Abhandlungen der Akademie der Wissenschaften in Berlin Annalen der Physik und Chemie Medicaminum Mercurialium Præcipua Classificatio Adjectis Nonnullis de Eorum Præparatione Chem. -Pharmac. Annotationibus, 1806 De Modis Arsenia Detegendi, 1812 Ueber die Wirkung des Lichts auf das Hornsilber, 1814 Ueber die Chemischen Reagentien, 1816 Chemische Untersuchungen der Heilquellen zu Salzbrunn, 1821 Ueber die Natur der Metallreduction auf Nassem Wege, 1828 Das Verhältniss der Chemischen Verwandtschaft zur Galvanischen Elektricität, in Versuchen Dargestellt, 1830 Systematischer Lehrbegriff der Chemie, in Tabellen Dargestellt, 1838

Worked examples

Example 1 — a first encounter with Nikolaus Wolfgang Fischer

Start with the simplest possible case. Write down what Nikolaus Wolfgang Fischer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nikolaus Wolfgang Fischer before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nikolaus Wolfgang Fischer ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nikolaus Wolfgang Fischer

In research: Nikolaus Wolfgang Fischer appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Nikolaus Wolfgang Fischer in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Nikolaus Wolfgang Fischer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1782 births, 1850 deaths, 18th-century German Jews, so understanding it makes those chapters shorter.
In everyday life: Look for Nikolaus Wolfgang Fischer outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
