Product - GCSE Chemistry Definition

Reviewed by: Richard Boole

Published

In GCSE Chemistry, a product is a new substance formed during a chemical reaction. The original substances that react are called reactants, and the substances made are the products.

For example:

Hydrogen + Oxygen → Water

In this reaction, water is the product.

Products can be elements or compounds, and they can be in any state of matter (solid, liquid, or gas). Understanding products helps explain how substances change and what new materials are formed in chemical reactions.

Richard has taught Chemistry for over 15 years as well as working as a science tutor, examiner, content creator and author. He wasn’t the greatest at exams and only discovered how to revise in his final year at university. That knowledge made him want to help students learn how to revise, challenge them to think about what they actually know and hopefully succeed; so here he is, happily, at SME.
