Title: Questions Regarding Wing Top and Bunsen Burner
Post by: Fizzle on September 25, 2005, 01:41:12 PM

Hi.

I'm a beginner in Chemistry and I'm a little stuck on a couple of questions I got for homework.

My first question is: Why does a luminous flame leave a deposit on a beaker? What does the deposit consist of?
I don't think I'm right, but what I got was that when methane gas (the fuel used) is mixed with oxygen, oxidation occurs and thus leaves carbon as the deposit.

My second question involves something called a wing top. I tried looking for information on it, but I honestly couldn't find anything. I'm asked what the function of the wing top is.

My last question is: Why doesn't a beaker or flask soften and melt in the bunsen burner flame?
I'm guessing it's because of the composition of the beaker/flask and that it may be fire-proof.

Thank you for any help I may get on this.  :D

oxidation is correct, but more precise would be incomplete combustion of the fuel leaving a "sooty" deposit.

those beakers/flasks have a high melting point, thats all.
