Describes a solution that has a relatively large amount of dissolved solute per solvent
concentrated
A solution that has a relatively large amount of dissolved solute per solvent is called a concentrated solution. Concentrated solutions contain a high ratio of solute to solvent molecules. These solutions have a higher concentration of solute particles, which can result in unique physical and chemical properties.
For example, concentrated hydrochloric acid has more hydrogen ions (H+) and chloride ions (Cl-) dissolved in water than dilute hydrochloric acid. This difference in concentration leads to different properties such as boiling point, freezing point, and acidity. Concentrated solutions can also be more reactive and potentially hazardous, requiring precautions when handling.
The concentration of a solution can be expressed in various ways, including mass percent, mole fraction, molarity, and molality. The choice of expression depends on the nature of the solute and solvent and the purpose of the solution. For instance, in a medical context, a concentrated saline solution may be prepared by dissolving a higher amount of sodium chloride in water. This solution is used for intravenous administration to replenish electrolytes and hydration.
Overall, a concentrated solution is one that has a relatively large amount of solute dissolved in a solvent, leading to unique properties and potential applications.
