A liquid in which one chemical has been mixed into another. Often solids are dissolved into a liquid. This means they are evenly spread through the fluid and stably stays that way. When a chemical is able to dissolve into a liquid, it is soluble. A measure of how well one chemical can dissolve into another is its solubility.
