What is "when a bunsen burner is properly adjusted?

When a Bunsen burner is properly adjusted, it exhibits the following characteristics:

  • Flame Color: The flame is typically a clear, light blue color. A yellow or orange flame indicates incomplete combustion. You can find information on flame color here.

  • Flame Shape: The flame has a distinct inner blue cone and a less defined outer cone. This shape indicates proper mixing of gas and air. Here you can see information about flame shape.

  • Noise Level: The burner produces a gentle, steady hiss, rather than roaring or sputtering. More info about noise level.

  • Temperature: The flame is at its hottest point just above the tip of the inner blue cone. Check more info about the temperature.

  • Luminosity: The properly adjusted flame is non-luminous, meaning it doesn't emit much light. A luminous, yellow flame indicates incomplete combustion and soot production. More info about luminosity.
