Sand and plastic are two solids that do not dissolve in water. Sand, composed mostly of silicon dioxide, remains as grains, while plastic, due to its polymer structure, retains its solid form in water.

FAQs & Answers

  1. What are some examples of solids that do not dissolve in water? Some examples of solids that do not dissolve in water include sand, plastic, metals like iron and aluminum, glass, and wood.
  2. Why do some solids not dissolve in water? Some solids do not dissolve in water because their molecular structure prevents interaction with water molecules, making them insoluble. For instance, the bonds in compounds like plastic or silicon dioxide (found in sand) are too strong to be broken by water.
  3. Are there any other materials similar to sand and plastic? Yes, other materials similar to sand and plastic that do not dissolve in water include gravel, ceramics, and certain types of non-water-soluble polymers.
  4. What is the importance of knowing which materials do not dissolve in water? Knowing which materials do not dissolve in water is important for various applications, including construction, environmental science, and waste management, as it affects material selection and disposal methods.
