Why is non luminous blue flame preferred over the luminous yellow flame in the laboratory?

blue flame is more important for laboratory procedures since it's also known as the reducing zone of the flame in which the tip of the blue flame has the highest temperature.

It produces more heat. It does not produce soot that would stain the laboratory apparatus.

Which bunsen burner luminous or non luminous flame used in laboratory and why?
The blue flame is used because it is the hottest.
How can a student change a luminowhat would need to be done to a Bunsen in order to change a luminous yellow flame into a non luminous blue flameus yellow flame into a non luminous blue flame?
A blue flame contains lots of oxygen compared to the yellow flame. So the only thing you should do is decrease the oxygen supply
Is the inner part of a luminous flame yellow?
The inner part of a flame burns blue while the outer part of the flame burns yellow.
What make gas flame luminous?
There is a lack of oxygen in the flame itself (most probably because of the air holes in the Bunsen burner or of your burning device) this effect would create a luminous flame (better known as a yellow flame). A kind of flame that does not burn as hot as a non-luminous flame (better known as a blue flame)
What colour is the Bunsen burner safety flame?
Yellow/Orange. The blue one is harder to see and hotter.
Should a luminous or non luminous Bunsen flame be used for heating in the laboratory and why?
Non-luminous flame should be used for heating in the laboratory because the flame is steady and produce little or no soot.Non-luminous flame is very hot thus, it is recommendable to use for laboratory purposes.Luminous flame is unsteady while non-luminous flame is steady.Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
Is non luminous flame steady or unsteady?
Non-luminous flame should be used for heating in the because the flame is steady and produce little or no soot. Non-luminous flame is very hot thus, it is recommen- dable to use for laboratory purposes. Luminous flame is unsteady while non-lumi- nous flame is steady. Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
How does luminous flame exist?
because of the yellow flame, yellow is a bright coulor........... Scientific term......... The collar is closed to get luminous flame and collar open to get non- luminous flame....
What color will a flame produce if there is limited air?
Limited oxygen intake in a lit Bunsen burner will emit a luminous, or yellow, flame. This type of flame is not usually used in the laboratory.
Which bunsen burner luminous or non luminous flame used in laboratory and why?
The blue flame is used because it is the hottest.
Which type of flame should use in laboratory luminous or non luminous?
Non- luminous flame should be used as it is steady and produces little or no soot.
What flame produce more soot and smoke?
the yellow flame

Characteristics of luminous flame?
Non luminous zone is the zone of a flame which is also the hottest zone of the flame as it is mostly in contact with oxygen. It is also called invisible zone.
What is luminous flame and Explain why it takes a longer time to heat equal amount of water using a luminous flame?
yellow color in a luminous flame produces soot or carbon. carbon dioxide is present in the luminous flame but when its combined with oxygen the flame is nonluminous which is in a blue color. it takes a longer time because luminous flame is cooler than the nonluminous. I only know what luminous flame is. The inner part of luminous flame is blue while the outer part of the luminous flame is yellow. It is unsteady. Yeah. Carbon Dioxide is only present in the luminous flame. When oxygen is combined with the flame, the flame will become non- luminous which is inner and outer part are blue. Hmm. Actually luminous flame's hottest part is at the bottom while non- luminous flame hottest part is at the middle and the top. That's all i know. If i know more, i will update for you. Thank you!

Is the inner part of a luminous flame yellow?
The inner part of a flame burns blue while the outer part of the flame burns yellow.
Which flame is not suitable for heating in Bunsen burner?
The yellow flame (or luminous flame) should not be used because 1. It is less hot that the blue flame (or non-luminous flame) 2. It produces soot, as compared to the blue flame which is the clean flame
