Solubility - GCSE Chemistry Definition

Solubility is a measure of how much of a substance can dissolve in a liquid to form a solution. When a substance, like sugar or salt, dissolves in a liquid, such as water, it breaks down into tiny particles that spread out evenly, and you usually can't see them any more. The solubility of a substance depends on the temperature and the type of liquid you are using. For example, sugar is more soluble in hot water than in cold water, which means you can dissolve more sugar in hot water. In GCSE Chemistry, understanding solubility helps you learn about how different substances interact and mix with each other.
