FAQs & Answers
- What determines if a substance is soluble or insoluble? Solubility depends on the chemical nature of the substance and the solvent, including molecular polarity, temperature, and pressure.
- Why is solubility important in environmental science? Solubility affects how pollutants dissolve and spread in water bodies, impacting ecosystems and water quality.
- Can a substance be soluble in one solvent and insoluble in another? Yes, solubility varies with the solvent; for example, oil is insoluble in water but soluble in organic solvents.
- How is solubility used in cooking? Solubility helps in dissolving ingredients like salt and sugar, influencing taste, texture, and chemical reactions during cooking.
