​

Answer 1

Answer:

Flame color determines the rate of combustion and thus there is a difference in temperature thereby producing a different color flame. ... This blue coloured zone is the non-luminous part of the flame. The reaction produces enough energy to excite and ionize gas molecules in the flame, leading to a blue appearance

Answer 2

Answer:

Question :

why a blue zone inside a flame is blue in colour?

Solution :

If observed carefully, a very small area near the base of the flame is blue. Since oxygen is not available for combustion in this area, carbon monoxide is formed as a result of incomplete combustion. The blue colour at the bottom is due to combustion of carbon monoxide.
