  1. Hace 3 días · The Bunsen burner is a staple in laboratories worldwide, essential for conducting experiments that require controlled heating. Named after the German chemist Robert Bunsen, who developed it in 1855, this device revolutionized laboratory practices by providing a safer and more controllable flame than its predecessors.

  2. Hace 5 días · Gustav Kirchhoff (left) and Robert Bunsen (right) Theory: Photoelectric flame photometry, a branch of atomic spectroscopy is used for inorganic chemical analysis for determining the concentration of certain metal ions such as sodium, potassium, lithium, calcium, Cesium, etc.

  3. Hace 1 día · Later, Robert Bunsen and Augustus Matthiessen isolated pure barium by electrolysis of a mixture of barium chloride and ammonium chloride. Radium. While studying uraninite, on 21 December 1898, Marie and Pierre Curie discovered that, even after uranium had decayed, the material created was still radioactive.

  4. Hace 2 días · Polyhedral Bunsen flames, induced by hydrodynamic and thermo-diffusive instabilities, are characterized by periodic trough and cusp cellular structures along the conical flame front. In this study, the effects of flow velocity, hydrogen content, and equivalence ratio on the internal cellular structure of premixed fuel-lean hydrogen/methane/air polyhedral flames are experimentally investigated ...

  5. Hace 6 días · Emil Behring, Ferdinand Cohn, Paul Ehrlich, Robert Koch, Friedrich Loeffler and Rudolph Virchow were among the key figures in the creation of modern medicine, while Koch and Cohn were also founders of microbiology.

  6. Hace 3 días · ..... To determine the concentration of certain metal ions such as sodium, potassium, lithium, calcium, Cesium, etc. and to understand the concept of flame reaction.

  7. Hace 4 días · Properly adjust the flame of the Bunsen burner. The proper flame is a small blue cone; it is not a large plume, nor is it orange. Wipe the glass slide with spirit and wave the slide over the Bunsen burner to remove any unwanted microorganisms in the slide.
