Determination of Boiling Point.
boiling Point of a liquid is the corrected temperature at which the vapour pressure of the liquid reaches 101.3 kPa.
in the flask 20 ml of the liquid being examined, add a few pieces of porous
material and heat rapidly to boiling.
Record the temperature at which liquid
beings to run from the side arm into the condenser.
temperature reading for the effect of barometric pressure using the following
t1 = t2 + K (101.3 – b)
t1 = the correct temperature
t2 = the measured temperature
the barometric pressure in kPa at the time of the determination
K = the correction factor
