Here's a breakdown:
* Solution: A homogeneous mixture of two or more substances.
* Solvent: The substance that dissolves the solute, usually present in a larger amount.
* Solute: The substance that gets dissolved in the solvent, usually present in a smaller amount.
For example, in saltwater:
* Saltwater is the solution.
* Water is the solvent (it's present in a greater amount).
* Salt is the solute (it's dissolved in the water).
