Dilution is the process of reducing the concentration of a substance in a solution. This is typically done by adding more solvent, such as water, to a solution containing a solute, like salt or sugar. As more solvent is added, the amount of solute remains the same, but its concentration decreases, making the solution less potent. In practical terms, dilutions are commonly used in laboratories and cooking. For example, when preparing a chemical solution for an experiment, a scientist may dilute a concentrated solution to achieve the desired concentration. Similarly, when making a drink, adding water to juice reduces its sweetness and intensity.
