* Solvent: The substance present in the larger amount, and it's the one that does the dissolving. Think of it as the "host" for the solute.
* Solute: The substance that gets dissolved. It's the "guest" that's being mixed into the solvent.
Example:
* When you make sugar water, water is the solvent (because there's more of it) and sugar is the solute (because it's being dissolved). The water dissolves the sugar, creating a sugar solution.
Key Takeaway: The solvent is the substance that does the dissolving, not the other way around.
