Solvent:
* Definition: A solvent is a substance that dissolves another substance, known as the solute, to form a solution.
* Key Characteristics:
* Solvents are usually liquids, but can also be gases or solids.
* They have the ability to break down the attractive forces holding the solute particles together.
* Examples:
* Water (H₂O): The most common solvent, often called the "universal solvent" due to its ability to dissolve many substances.
* Ethanol (C₂H₅OH): Used in alcoholic beverages, perfumes, and many cleaning solutions.
* Acetone (CH₃COCH₃): A powerful solvent found in nail polish remover.
* Hexane (C₆H₁₄): Used in extracting oils and fats.
Dissolve:
* Definition: To dissolve means for a solute to break apart into individual particles (molecules, ions, etc.) and become evenly dispersed throughout the solvent.
* How it Works:
* The solvent's molecules surround the solute particles, forming a weak attraction (called solvation).
* This interaction weakens the forces holding the solute together, causing it to break apart.
* The result is a homogeneous mixture called a solution.
* Examples:
* Sugar dissolving in water: Sugar molecules break down and disperse throughout the water, creating a sugar solution.
* Salt dissolving in water: Salt crystals break into sodium (Na⁺) and chloride (Cl⁻) ions, which are surrounded by water molecules.
Important Notes:
* Solubility: The degree to which a solute dissolves in a solvent is called its solubility. Some substances are highly soluble (like sugar in water), while others are barely soluble (like oil in water).
* Polarity: The polarity of the solvent and solute plays a big role in solubility. "Like dissolves like" means that polar solvents (like water) tend to dissolve polar solutes (like sugar), while non-polar solvents (like oil) tend to dissolve non-polar solutes (like fats).
