Question

how do you prove that unburnt carbon particles are present in the luminous zone of the flame? Describe an experiment
​

Answer 1

Answer:

Explanation:

The circular dark ring is formed on the slide by deposition of unburnt carbon particles present (middle) luminous zone of the candle. The copper wire takes the least time to become red hot when introduced into the (outermost) non luminous zone of the flame as this zone has the highest temperature.

In the simplest case, the yellow flame is luminous due to small soot particles in the flame which are heated to incandescence. ... To produce enough soot to be luminous, the flame is operated at a lower temperature than its efficient heating flame (see Bunsen burner).

The heat and light given off are characteristic of the specific chemical reaction (or reactions) going on; the luminosity of the flame is usually caused by solid particles of foreign matter present (naturally or artificially) in the burning gas and heated to incandescence
