Soluble - GCSE Chemistry Definition

Reviewed by: Richard Boole

Published

In chemistry, the term "soluble" refers to a substance's ability to dissolve in a liquid, usually water. When a substance dissolves, it breaks down into tiny particles that mix evenly with the liquid, forming a solution. For example, sugar is soluble in water because it disappears when stirred in and sweetens the liquid. Solubility is important in chemistry because it helps us understand how substances interact in different conditions. Knowing if something is soluble helps in predicting how it will behave in chemical reactions or how it can be used in various applications.

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.
