Here's a breakdown:
* Solute: The substance that dissolves (e.g., sugar, salt).
* Solvent: The substance that does the dissolving (e.g., water).
* Solubility: The maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature and pressure.
Factors affecting solubility:
* Temperature: Generally, solubility increases with increasing temperature.
* Pressure: Pressure mainly affects the solubility of gases. Higher pressure leads to higher solubility.
* Nature of the solute and solvent: "Like dissolves like" - polar solutes dissolve in polar solvents, and nonpolar solutes dissolve in nonpolar solvents.
* Presence of other solutes: Adding other solutes can influence the solubility of the original solute.
Measuring solubility:
Solubility is usually expressed as:
* Grams of solute per 100 grams of solvent: This is a common way to measure solubility.
* Molarity: Moles of solute per liter of solution.
* Parts per million (ppm) or parts per billion (ppb): These units are used for very low concentrations.
Understanding solubility is crucial in various fields, including chemistry, pharmacy, biology, and environmental science.
