Principle of Boiling

point test

 A sample is heated

gradually in a tube which is

immersed in a liquid bath.

The sample tube is held in

close contact with a

thermometer and it contains

a boiling capillary which is

fused about 1 cm above its

lower end. Upon approach

of the boiling temperature

bubbles emerge rapidly

from the lower open end of

the capillary. The boiling

temperature is that

temperature at which, on

momentary cooling, the

string of bubbles stops and

liquid suddenly rises in the

capillary.
