Electrolysis: A Science Project

Electrolysis: A Science Project | Science Fair Projects | STEM Projects
Have you ever wondered how electricity can be used to create gas? In this project, you'll explore the process of electrolysis and discover how to use electricity to create hydrogen gas.


The hypothesis is that a higher DC voltage applied to the electrolysis process will increase the rate at which hydrogen gas is produced.

Method & Materials

You will use a beaker, tap water, salt, batteries, test tubes, and other materials to conduct the experiment.
You will need a beaker, tap water, salt, batteries, test tubes, and other materials.


The results of this experiment show that increasing the DC voltage will result in a faster release of gasses from the chemical reaction in the electrolyte. However, increasing the amount of salt in the electrolyte does not change the rate of gas released from the electrolysis process.

Why do this project?

This science project is interesting because it explores the process of electrolysis and how electricity can be used to create gas.

Also Consider

Consider experimenting with different types of electrolytes such as vinegar or sulfuric acid. Also, examine the effects of raising or lowering the temperature of the solution during the process of electrolysis.
