Solubility is the ability of a substance to dissolve in a solvent, like sugar dissolving in water. It tells us how much of that substance can be dissolved at a certain temperature. Understanding solubility helps in everyday activities like cooking and in scientific experiments.
FAQs & Answers
- What factors affect solubility? Solubility is affected by temperature, pressure, and the nature of the solute and solvent. For example, most solids dissolve better in warmer liquids, while gases are more soluble under higher pressures.
- How is solubility measured? Solubility is typically measured in grams of solute per 100 grams of solvent at a specific temperature. This helps determine how much of a substance can dissolve.
- What is a saturated solution? A saturated solution is one where no more solute can dissolve in the solvent at a given temperature, indicating that the solvent has reached its capacity to hold dissolved substance.
- Why is solubility important in everyday life? Understanding solubility is crucial in cooking, pharmaceuticals, and environmental science, as it influences how substances interact and can be effectively utilized.
