What Are 5 Compounds That Are Insoluble in Water? Key Examples Explained

Discover five common compounds insoluble in water including calcium carbonate and silver chloride, and learn why they resist dissolving.

6 views

Five compounds that are insoluble in water include calcium carbonate (CaCO3), used in construction; lead(II) sulfate (PbSO4), found in some batteries; silver chloride (AgCl), used in photographic processes; barium sulfate (BaSO4), a radiopaque agent in medical imaging; and iron(III) hydroxide (Fe(OH)3), often resulting from water treatment processes. These compounds do not dissolve well in water due to their strong ionic bonds or molecular structures that water molecules cannot easily surround and pull apart.

FAQs & Answers

  1. What causes a compound to be insoluble in water? A compound is insoluble in water primarily due to strong ionic bonds or molecular structures that prevent water molecules from surrounding and breaking them apart effectively.
  2. Are all metal compounds insoluble in water? No, not all metal compounds are insoluble; solubility depends on the specific compound’s chemical structure and bonding. For example, sodium chloride is highly soluble, while calcium carbonate is insoluble.
  3. What are common uses for water-insoluble compounds? Water-insoluble compounds are used in various applications such as construction (calcium carbonate), medical imaging (barium sulfate), and photography (silver chloride) due to their stability and physical properties.
