What happens to the flame of a Bunsen burner when there is an adequate supply of oxygen available to react with the fuel

When an adequate supply of oxygen is available to react with the fuel of a Bunsen burner, there is complete combustion of the fuel and a non-luminous flame is produced.

Complete combustion occurs where there is plentiful supply of oxygen. During the reaction, more heat energy is produced as the flame is non-luminous and less soot is produced.

A non-luminous flame is a flame which produces less light but more heat energy. It is usually blue in color and consists of three zones. These zones are:

1. The zone of unburnt gas.

2. The luminous zone.

3. The outermost non luminous zone.

Explanation:

When there is an adequate supply of oxygen available to react with the fuel of a bunsen burner, the flame produce is a non luminous bunsen flame.

This flame i.e non luminous flame produced is much hotter than the luminous and three zones can be seen in the flame. This zones are

1. The zone of unburnt gas.

2. The luminous zone.

3. The outermost non luminous zone.
