To prepare a salt solution, we need to dissolve a solute (salt) in a solvent (water). The solvent is the substance that dissolves the solute. In this case, water is the solvent. The solute is the substance that is being dissolved. In this case, salt is the solute.

The process of preparing a salt solution involves the following steps:

1. Obtain the desired amount of salt and water.

2. Add the salt to the water.

3. Stir the mixture until the salt is completely dissolved.

The resulting solution is a homogeneous mixture of salt and water. The salt is now evenly distributed throughout the water. The concentration of the salt solution is determined by the amount of salt that is dissolved in the water.
