experiment
Into one chamber of an electrochemical cell, a solution of X is introduced, along
with a metal electrode. In the other chamber a solution of a known oxidizing
reagent O is introduced, along with another metal electrode. The voltage across
the electrodes is proportional to the tendency of O to react with X. By measuring
this voltage, the value of R may be calculated.
A sample of X is melted and put into a reservoir from which a very thin tube leads
down. The rate at which X flows out of the tube is measured, and from this rate
the value of V may be calculated.
A sample of X is carefully weighed and put inside a sealed calorimeter. The
calorimeter is heated electrically, and the amount of heat added determined by
monitoring the electrical current used. The temperature of X is carefully measured,
and from the temperature change and the amount of heat added the value of H
may be calculated.
