Here's the breakdown of solute and solvent in a copper sulfate solution:

* Solute: Copper sulfate (CuSO₄)

* Solvent: Water (H₂O)

Explanation:

* Solute: The substance that dissolves in a solution. In this case, copper sulfate is the solid that dissolves in the water.

* Solvent: The substance that dissolves the solute. Water is the liquid that dissolves the copper sulfate, forming a solution.

Think of it this way: You're adding a small amount of copper sulfate (the "stuff" you want to dissolve) to a larger amount of water (the "dissolving agent").
