Experiment no.1
Study of Bunsen burner and glass work
A) Study of Bunsen burner
The different parts of Bunsen burner are:a) The base:- It has a side tube for the entry of the gas and a nozzle at the upper part for the escape of the gas.(fig-a)
b) Burner tube: - It is a cylindrical tube with two air holes. The gas sucks air, while it moves to the top of the burner tube. (fig-b)
c) Air regulator: - It is a metal ring around the burner tube .By turning the air regulator round the burner tube, the air holes will be opened or closed completely or partially and the supply of air can be regulated. (fig-c)
Working of Bunsen burner: - the three different parts of the burner are reassembled and the burner is connected to the gas supply. The air holes are closed using air regulator and the gas is lighted.
It forms a luminous yellow flame. (Fig-d)
A luminous flame has 3 zones:1. A dark inner zone of non-combustion.
2. A luminous middle zone of incomplete combustion.
3. A faintly luminous outer zone of complete combustion.
Formation of non-luminous flame
The air holes are opened gradually by turning the air regulator until a non-luminous blue flame is obtained. (Fig-e)
A non-luminous flame has 3 zone
1. A dark region of unburnt gases.
2. A small blue region on the base of the flame.
3. A pale blue outer zone of complete combustion
