The Bunsen Burner Lab Essay

1009 words - 5 pages

PURPOSE:The purpose of this experiment was to demonstrate the characteristics of a Bunsen burner flame. There are two types of flames having different characteristic to be studied. The two types of flames are as follows:1.The Luminous Flame2.The Non-Luminous FlameHYPOTHESIS:The Luminous Flame will have yellow/orange, normal as when a splint is lighted. All flames are stable when hold still. There should be no noise after the Bunsen burner is lighted. Non- Luminous Flame would be the same but have little different reaction, typically having the same characteristics. If the Nichrome wire is passes through both types of flames, it will indicate the amount of heat given off by different regions ...view middle of the document...

9.The observation was noted down.10.Turned off the gas. Carefully push the t-pin through the matchstick (about 0.5cm from the top of the head of the match).11.Pin was placed exactly at the center of the barrel, then the gas was turned on full and the spark was made at the top of the barrel to produce the flame. All the observation was written down.12.The matchstick was removed after the barrel had cool down and everything was returned to the front. Leave nothing in the sink.OBSERVATIONS:Types of flameLuminous flameNon-luminous flameCharacteristics of flames ·Blue and the tip of the flame was orange·Wavy·Low hissing noise ·Warm flame·Blue flame with an inner light blue cone·Steady·High hissing noise·Very hotNichrome wire testNot tested·Hot outer region turned orange·Cold inner cone turned blueT-pin and matchstickNot tested·It didn’t burn because the temperature was low and carbon dioxide (CO2) gas was present.ANALYSIS:·State three safety practices when using the Bunsen burner:1)Do not use a Bunsen burner near wooden shelves, flammable liquids, or any other items that is highly flammable.2)Before using a Bunsen burner make sure that long hair is tied back and wear safety goggles.3) Do not wear loose clothing, chain, or watches.·The observation about the inner blue cone of flame from the T-pin matchstick investigation:Matchstick didn’t burn/light up because the temperature of inner blue cone is low and CO2 is present. Inner blue cone of non-luminous flame is cool part of the flame and...

Why did some chemicals create a bright yellow flame, while other chemicals created an intense red color flame? In 1854, he teamed up with German scientist Gustav Robert Kirchhoff to help find a reasoning behind this phenomenon (Scratch). Kirchoff suggested to take the light from the flame, and shoot it through a prism. Together they found that the prism would
