"Solution ans" is not a standard term. Assuming "ans" is intended to represent the word "answer," and the question is asking for the definition of a solution, then the answer is:
A solution is a homogeneous mixture formed when one or more solutes dissolve completely into a solvent.
Here's a breakdown of the components:
-
Solute: The substance that dissolves. Examples include sugar dissolving in water or salt dissolving in water.
-
Solvent: The substance that dissolves the solute. It's typically the component present in the greatest amount. Water is a very common solvent (often called the "universal solvent").
-
Homogeneous mixture: A mixture where the components are evenly distributed throughout, resulting in a uniform composition. You cannot see the individual solute particles after they have dissolved in the solvent.
Key Characteristics of Solutions:
- Homogeneity: The mixture is uniform throughout.
- Particle Size: Solute particles are very small (ions, atoms, or molecules).
- Clarity: Solutions are usually clear (though they can be colored).
- Stability: Solutes do not settle out of the solution over time.
- Filtration: Solute particles cannot be separated from the solvent by filtration.
Examples of Solutions:
| Solution | Solute(s) | Solvent |
|---|---|---|
| Saltwater | Salt (NaCl) | Water |
| Sugar Water | Sugar (Sucrose) | Water |
| Air | Oxygen, etc. | Nitrogen |
| Brass (an alloy) | Zinc | Copper |
