Solutions
* Homogeneous: The components are evenly distributed throughout the mixture. You can't see the individual components with the naked eye.
* Uniform composition: The concentration of the components is the same throughout the mixture.
* Stable: The components remain mixed and don't settle out over time.
* Components are chemically bonded: The solute particles dissolve into the solvent, forming a new chemical entity.
* Examples: Saltwater, sugar dissolved in water, air
Mixtures
* Can be heterogeneous or homogeneous: The components may or may not be evenly distributed.
* Non-uniform composition: The concentration of the components may vary throughout the mixture.
* May not be stable: The components may settle out over time.
* Components are not chemically bonded: The components simply mix together, but they retain their individual properties.
* Examples: Sand and water, oil and water, a salad
Here's a simple way to think about it:
Imagine making a cup of coffee. You're adding coffee grounds to water.
* Solution: When the coffee grounds dissolve in the water, creating a uniform brown liquid, you have a solution.
* Mixture: When you add milk to the coffee, you have a mixture. You can still see the separate components of milk and coffee.
In summary: Solutions are a specific type of mixture with the key characteristic of being homogeneous and having a uniform composition. All solutions are mixtures, but not all mixtures are solutions.
