What did Robert Bunsen have to do with the Bunsen burner?

Using his burner, Bunsen used flame tests to analyze substances much more reliably than ever before. The burners he designed were made by Peter Desaga, his laboratory assistant. Bunsen published the design of the burner in 1857, but did not patent his design. His burner is now used not only for flame tests.

What is Robert Bunsen best known for?

Robert Bunsen, in full Robert Wilhelm Bunsen, (born March 30, 1811, Göttingen, Westphalia [Germany]—died August 16, 1899, Heidelberg), German chemist who, with Gustav Kirchhoff, about 1859 observed that each element emits a light of characteristic wavelength.

What did Robert Bunsen invent or discover?

Caesium
Rubidium
Robert Bunsen/Discovered

In 1860 Robert Bunsen and Gustav Kirchhoff discovered two alkali metals, cesium and rubidium, with the aid of the spectroscope they had invented the year before. These discoveries inaugurated a new era in the means used to find new elements.

Who invented the Bunsen?

Robert Bunsen
Bunsen burner/Inventors
Science historian Howard Markel talks about the German chemist Robert Bunsen, and why his experiments necessitated the invention of the gas burner still in use today. UNIDENTIFIED MAN: The alphabet has only 26 letters. With these 26 magic symbols, however, millions of words are written every day.

Where did Mr Bunsen lose his eye?

He accepted an associate professorship at the University of Marburg where he became a full professor in 1841. He continued his experiments with cacodyl derivatives. Cacodyl is extremely toxic and spontaneously combusts in dry air. A cacodyl explosion left Bunsen blind in his right eye.

What is a Bunsen burner used for?

Bunsen burner, device for combining a flammable gas with controlled amounts of air before ignition; it produces a hotter flame than would be possible using the ambient air and gas alone.

What gas is used in Bunsen burners?

Bunsen burners provide a flame with temperatures up to 1’200°C. Natural gas (primarily methane), liquefied petroleum gas such as propane, butane or a mixture of both are used as fuels. The gas flows through a small opening at the base of the barrel and is directed upwards.

Why is it called a Bunsen burner?

Named for Robert Bunsen, the German chemist who introduced it in 1855 (from a design by Peter Desdega, who likely modified an earlier design by Michael Faraday), the Bunsen burner was the forerunner of the gas-stove burner and the gas furnace.

What did Robert Bunsen study in university?

Bunsen began school in Göttingen but transferred to the Gymnasium at Holzminden, from which he graduated in 1828. Returning to Göttingen, Bunsen entered the university, where he studied chemistry physics, mineralogy, and mathematics. His chemistry teacher was Friedrich Stromeyer, who had discovered cadmium in 1817.

Why is a blue flame preferred over a yellow?

If the air hole is closed there is a shortage of oxygen. Combustion is incomplete and less energy is transferred. A blue flame from a Bunsen burner transfers more energy than a yellow Bunsen flame as complete combustion gives a blue flame. This is because a yellow flame produces a lot of soot.

What is a blue flame called?

The LPG (propane) is a blue flame because complete combustion creates enough energy to excite and ionize the gas molecules in the flame.

Are Bunsen burners still used today?

Bunsen burners are now used in laboratories all around the world.

Why did Robert Bunsen invent the Bunsen burner?

Working along with his laboratory assistant Peter Desaga, Robert Bunsen designed a burner that produces a single open gas flame, which is used for heating, sterilization, and combustion. The burners, known as Bunsen burners, are used in laboratories all around the world.

Who was Robert Bunsen and what was his background?

Robert Wilhelm Eberhard von Bunsen was born on March 31, 1811, in Gottingen, Germany. His father was professor of linguistics and head librarian at the University of Gottingen while his mother was a housewife. Through his father, Bunsen was exposed to an academic background early on.

What did Robert Bunsen and Peter Desaga do?

With his laboratory assistant, Peter Desaga, he developed the Bunsen burner, an improvement on the laboratory burners then in use. The Bunsen – Kirchhoff Award for spectroscopy is named after Bunsen and Kirchhoff.

What did Robert Bunsen do with Gustav Kirchhoff?

Bunsen’s friend and colleague Gustav Kirchhoff was interested in the infant science of spectroscopy. Spectroscopy was the science of splitting sunlight into the colors of the rainbow using a prism – much as Isaac Newton did in 1666. A prism splits a beam of sunlight into a colored spectrum of light.
