1. Important Vocabulary Words for Mixtures and Solutions

2. Dissolving
We say a substance ______________if it spreads apart when added to a solvent (like water) so we can’t crystals/grains anymore.
Dissolving is a complex physical and chemical process!
The substance is still there! We just can’t see it because it has spread apart.
Question: How is dissolving different from melting?
Answer:

3. Solubility
A substance is ____________if it dissolves in water. Example: We observed in class that rock salt is ____________in water. After adding it to water, it spreads apart so we can no longer see it!

4. Solubility
