Testing for Hydrogen Gas Practical

Testing for Hydrogen Gas – Squeaky Pop Test Practical

Give students hands-on experience producing and testing hydrogen gas with this ready-to-use Chemistry practical.

Students react magnesium ribbon with dilute hydrochloric acid, collect the gas and use a lit splint to test for hydrogen. They record their observations, answer structured questions and complete a guided conclusion to consolidate their understanding of the reaction.

What is included:

• A clear, step-by-step method with a labelled diagram.
• An aim, equipment list and safety guidelines.
• An observations table for recording results.
• Five structured questions, including a word equation activity.
• A cloze-style conclusion to reinforce key scientific vocabulary.
• Colour and black-and-white printer-friendly versions.
• A two-page PDF and an editable Microsoft Word document.

Why use this resource?

• Develops practical skills and scientific observation.
• Reinforces the identification test for hydrogen gas.
• Provides structured support for recording and interpreting results.
• Requires minimal preparation and is ready to print.
• Includes an editable version for teachers who wish to adapt the activity.

Suitable for: KS3 Science, junior secondary Chemistry, and introductory chemical reactions and gas tests.

Safety note: This practical involves dilute hydrochloric acid and a flammable gas. Appropriate eye protection, teacher supervision and school laboratory safety procedures are essential.
