Experiment No: 1
Name of the Experiment: Measurement of Hydrogen Volume and Production rate through
Electrolysis of Water Using NaOH as an Electrolyte
Summary:
Hydrogen gas is produced from water through electrolysis using electrolyte (NaOH) of a certain
concentration to ensure rapid result. A 220-240 AC voltage is used as power source for the
electrolysis process. The process is conducted according to Faraday’s law of electrolysis. The
used volume of water is 3/4th of the cylinder used. The volume of both water and volume
occupied by hydrogen is measured carefully using proper equipment. Produced gas is collected
underwater to ensure accurate measurement of volume.
Conclusion:
The experiment demanded to determine how the applied current affected the rate of hydrogen
gas production. An electrolysis cell, two electrodes (one cathode and one anode), a power
supply, and a gas collecting system were all used in the experiment. To act as an electrolyte and
aid in the conduction of electricity, NaOH was added to the water.
When water is electrolyzed using NaOH as the electrolyte, the experimental set-up and
techniques used in this lab were successful in measuring the volume of hydrogen gas created and
figuring out the rate of hydrogen gas generation. The information gathered helped to shed light
on how the applied current and the rate of hydrogen gas generation are related
