1. Solute: The substance that is being dissolved. Examples include sugar, salt, or coffee grounds.
2. Solvent: The substance that dissolves the solute. The most common solvent is water, but others exist like alcohol or oil.
3. Dilute Solution: A solution where the concentration of the solute is low relative to the solvent.
Here's how it works:
* Dissolving: When you add the solute to the solvent, the solute particles break apart and become evenly distributed throughout the solvent.
* Concentration: The concentration of a solution is a measure of how much solute is dissolved in a given amount of solvent. A dilute solution has a low concentration of solute.
Example:
Imagine you're making sugar water. You add a teaspoon of sugar (solute) to a glass of water (solvent). This creates a dilute solution because there is a small amount of sugar compared to the large amount of water.
Key Points:
* Dilute solutions are often described as "weak" solutions.
* The opposite of a dilute solution is a concentrated solution, which has a high concentration of solute.
* You can make a dilute solution by:
* Adding more solvent to a concentrated solution.
* Adding a small amount of solute to a large amount of solvent.
