Here's a breakdown:
* Solute: The substance that dissolves in a solvent.
* Solvent: The substance that dissolves the solute, creating a solution.
* Concentration: The amount of solute dissolved in a given amount of solvent.
Example: Imagine a glass of sugar water.
* Solute: Sugar
* Solvent: Water
* Concentration: The amount of sugar dissolved in the water.
If you add more sugar (solute) to the water, the concentration of sugar in the solution increases. However, the concentration of water (solvent) decreases proportionally. This is because the total volume of the solution remains the same, but the proportion of each component changes.
Key points:
* Total concentration: The sum of solute and solvent concentrations always remains constant within a solution.
* Units of concentration: Concentration is typically expressed as molarity (mol/L), molality (mol/kg), or percentage (% by mass or volume).
In summary:
The relationship between solute and solvent concentrations is an inverse one. As one increases, the other decreases, maintaining a constant total concentration within the solution.
