A layer of excess carbon (soot) can be deposited on a tube if the Bunsen flame is yellow instead of blue. The yellow color indicates incandescent carbon particles, due to insufficient oxygen in the gas-air mix. Opening the collar wider will admit more air to the base of the flame and improve combustion (a hotter blue flame) so that more of the gas's carbon is oxidized.

What is the name for the thing that holds a test-tube over a Bunsen burner?
tongs
What is a Bunsen burner and its function?
A Bunsen burner is a device that is used to heat materials in science. It uses a flow of gas and an air hole to regulate the temperature of the flame.
Does a Bunsen burner measure anything?
its used for heating up test tubes and other lab equipment
When heating a test tube one should always use this piece of safety equipment?
A Bunsen Burner. ******************* Safety glasses
What are the functions of flames produced by a Bunsen burner?
A Bunsen burner is designed to produce a focused, hot flame in a way that radiates heat up, and not out. This means it is very useful for heating up a small sample of matter (like in a test tube), but for it still to be safe enough to handle in close quarters.
How do you put a test tube on a Bunsen burner?
The Bunsen burner goes under a thin, fireproof chemistry table.
What kind of object is a Bunsen?
a bunsen is a type of burner used to heat test tube
What element in the flame test was excited using a Bunsen burner?
Examples: Na, K, Li, Cs, Ba, Ca, etc.
What is the name for the thing that holds a test-tube over a Bunsen burner?
tongs
Why are all manipulations of bacteria culturing carried out next to a lit Bunsen burner?
The lit Bunsen burner is used to sterilize the loop, needle, and the openings of test tubes containing cultures, or that will be inoculated.
What is a Bunsen burner and its function?
A Bunsen burner is a device that is used to heat materials in science. It uses a flow of gas and an air hole to regulate the temperature of the flame.
What kind of testing can the Bunsen burner be used for?
An example is the flame test, a method of qualitative analysis.
Does a Bunsen burner measure anything?

What equipment is used to hold a test tube in the Bunsen burner flame?
faith in the lord and juses is important
How do you test for lithium?
Flame Test: heat up with a bunsen burner and the lithium ion fives off a crimson flame, proving it it lithium.
What is a Bunsen burner?
A Bunsen Burner is a controlled gas-burning heat source (a "gas candle") that supplies direct heat or flame for scientific experiments and research. (The flame can be blocked by screens to reduce the deposition of soot on test tubes and beakers.)
When heating a substance over a Bunsen burner where should the object be placed for the most efficient heating?
When heating a substance over a Bunsen burner the iron clamp for test tubes or the wire gauze is placed on top of the iron ring for beakers.
