<u>Answer:</u> The solute, salt must dissolve in the solvent, water.
<u>Explanation:</u>
Solute is defined as the substance which is present in smaller proportion in a solution.
Solvent is defined as the substance which is present in larger proportion in a solution.
Solution is the combination of solute and solvent.
In a solution, a solute will always dissolve in solvent.
We are given:
Salt and water to form a solution. Here, salt is present in smaller proportion, so it is a solute and water is a solvent.
Hence, the solute, salt must dissolve in the solvent, water.
