Why does the wire not glow in the hottest part of the Bunsen burner flame?

Click For Summary
SUMMARY

The discussion centers on the observation that a Nickel Chromium wire does not glow in the hottest part of a Bunsen burner flame, specifically the blue triangle flame, while it glows red/orange in the cooler yellow/orange part. Participants noted that the wire should glow regardless of the flame's temperature, leading to confusion. The teacher suggested that oxygen levels in the flame may play a role in this phenomenon, indicating that the wire's glowing is affected by the combustion environment rather than solely temperature.

PREREQUISITES
  • Understanding of combustion chemistry
  • Familiarity with Bunsen burner operation
  • Knowledge of metal properties, specifically Nickel Chromium
  • Basic principles of thermal radiation
NEXT STEPS
  • Research the role of oxygen in combustion reactions
  • Explore thermal radiation and its relation to temperature
  • Investigate the properties of Nickel Chromium wire under different temperatures
  • Learn about flame types and their characteristics in chemistry
USEFUL FOR

This discussion is beneficial for high school chemistry students, educators, and anyone interested in the principles of combustion and thermal properties of materials.

In our high school Chem 1 Class, we had this lab where we went around doing simple

experiments and determining whether the change was a physical one or a chemical one. Well,

when one of the stations had be perplexed. At this station we had a Nickel Chromium

Wire with an Aluminum handle, and what we had to do was put the wire in the Bunsen burner.

When I put the wire part into the yellow/orange part near the top of the burner, the wire, like

expected, quickly glowed red/orange (Like burning embers). When I put it in the hottest part or

the burner at the blue triangle flame, the wire did not glow. I asked my teacher and he said the

wire should have glowed at any part of the flame, yet it did not. He tried the experiment and

got the same result. So, why does the wire glow in the red/orange part of the flame, but not

the hottest part?

Any ideas of what is going on?
 
I think my teacher said something with Oxygen when he tried to give an answer.
 
Any ideas?
 
It should glow, no doubt about it. Hard to say what you have seen and interpreted as "no glow". I am not saying you didn't saw what you saw.
