The correct answer to the question is:
- If something CAN dissolve into another thing, we call it soluble.
- If something CANNOT dissolve into another thing, we call it insoluble.
Explanation:
1. Soluble: This term is used to describe a substance that has the ability to dissolve in a particular solvent. For example, sugar is soluble in water because it can dissolve in water to form a homogeneous mixture.
2. Insoluble: On the other hand, this term is used for a substance that does not dissolve in a specific solvent. An example of an insoluble substance is sand, which does not dissolve in water and settles at the bottom of the container without forming a solution.
So, when a substance has the ability to dissolve in a particular solvent, it is referred to as soluble. Conversely, when a substance cannot dissolve in a specific solvent, it is termed as insoluble.
