* Concentration decreases: The amount of solute (the dissolved substance) remains the same, but the total volume of the solution increases. This results in a lower concentration of solute per unit volume.
* Solution becomes less viscous: Concentrated solutions tend to be more viscous (thick) than dilute solutions. Adding solvent reduces the viscosity.
* Chemical reactions might be affected: The rate of chemical reactions can be influenced by the concentration of reactants. Dilution generally slows down reactions.
* Solubility might be affected: Adding solvent can sometimes affect the solubility of the solute. In some cases, it might lead to precipitation if the solution becomes supersaturated.
Example:
Imagine you have a concentrated sugar solution (syrup). If you add a large amount of water (solvent), the sugar concentration will decrease, making the syrup less sweet and less viscous.
Key takeaway: Adding solvent to a concentrated solution always results in a dilution, leading to a decrease in concentration and other related changes.
