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.
