<h3><u>Answer;</u></h3>
Atomic particles
The first step in the two-step process of making a solution is the breakdown of the solute source into <u>atomic particles</u>.
<h3><u>Explanation</u>;</h3>
- Solution is a homogeneous mixture of two or more substances uniformly dispersed throughout a single phase
- <em><u>The liquid component that makes up the largest part of a solution is called the solvent, and the substance that is dissolved is called the solute.</u></em>
- Unsaturated Solution is a solution that contains less solute than a saturated solution does and that is able to dissolve additional solute, while saturated Solution is a solution that cannot dissolve any more solute under the given conditions
