    Study Notes

    Bunsen Burner Components

    • Flame (Outer Cone)

      • The outer cone of the flame is where complete combustion occurs, producing a hotter and non-luminous flame.
    • Flames (Inner Cone)

      • The inner cone is the hottest part of the flame, typically characterized by a blue color due to efficient and complete combustion of gas.
    • Barrel or Chimney

      • The vertical tube that connects the flame to the gas source, facilitating gas and air mixing for combustion.
    • Collar

      • Adjustable component that regulates the amount of air mixed with gas, affecting the flame type and temperature.
    • Base

      • The sturdy support structure that stabilizes the Bunsen burner and prevents tipping during use.
    • Rubber Tubing

      • Flexible connector that transports gas from the gas source to the burner, essential for safe and effective operation.
    • Air Hole

      • An opening located on the barrel that allows air to enter and mix with the gas, critically influencing flame characteristics.
    • Gas Valve

      • Controls the flow of gas into the burner; adjusting this valve alters the flame's size and intensity.
    • Heat Proof Surface

      • A resistant surface under the Bunsen burner to protect the lab bench from heat damage during experiments.
