Examples of insoluble substances include calcium carbonate (CaCO3), found in chalk and limestone, barium sulfate (BaSO4), used in radiology, silver chloride (AgCl), used in photographic processes, and iron(III) oxide (Fe2O3), a common rust. These substances do not dissolve in water, making them crucial in various industrial and scientific applications due to their stability in aqueous solutions.
FAQs & Answers
- What does it mean when a substance is insoluble? An insoluble substance is one that does not dissolve significantly in a solvent, such as water, resulting in little to no formation of a solution.
- Why is calcium carbonate insoluble in water? Calcium carbonate is insoluble in water because it forms a stable solid lattice that does not break apart easily, limiting its ability to dissolve.
- Where is silver chloride commonly used? Silver chloride is commonly used in photographic processes due to its light-sensitive properties.
- How are insoluble substances important in industry? Insoluble substances are used in various industries for their stability and resistance to dissolution, such as in radiology imaging with barium sulfate and in construction materials like chalk and rust.
