Bunsen Burner Lab: Tools of the Physical Scientist Background: Often a chemist needs to heat materials. The Bunsen Burner is one of the most efficient ways of doing this. Burners come in a variety of designs but most operate by the combustion of gas with air to produce a hot flame. A properly adjusted flame consist of two cones; an outer light blue and an inner dark blue cone. The inner cone

It is the result of excited molecular radicals in the flame, which mostly emit their light in the blue spectrum. A candle flame is a good example. At the base of the wick, the flames will be blue. Farther away, there will be less molecular radicals and more soot, resulting in yellow flames. You won't see all of the colors of the spectrum, because they have less to do with the black body
- The Bunsen burner has a colar that you can turn to open or close an air hole. The air hole allows the air from the room to be drawn into the chimney and mix with the gas and therefore allow a plentiful supply of oxygen for the gas to react with. That results in complete combustion. methane + oxygen > carbon dioxide + water . A very hot, noisy, non-luminous, roaring blue flame is produced. In
- The Bunsen Burner Worksheet Introduction Sometimes when you do experiments in the laboratory you have to heat or burn things. The most convenient way is to use a Bunsen burner.
- To perform a flame test a powdered sample of chemical (see list below) is placed onto a platinum or Nichrome wire loop and suspended in a Bunsen burner (or propane torch) flame. It is important to first clean the wire loop in the flame so no contaminating dust interferes with the true color of the test sample flame.
- c Sterilise a wire loop by heating to red hot in a roaring blue Bunsen burner flame before and after use. This ensures that contaminating bacterial spores are destroyed. This ensures that contaminating bacterial spores are destroyed.
