FAQs & Answers

  1. What makes a substance water soluble? A substance is water soluble if it can dissolve in water due to its ability to interact and form bonds with water molecules, often because of polarity or ionic characteristics.
  2. Why are salt and sugar water soluble? Salt (sodium chloride) dissolves in water because it breaks into ions that interact with water molecules, while sugar dissolves due to its polar molecules forming hydrogen bonds with water.
  3. Is alcohol soluble in water? Yes, alcohol, such as ethanol, is soluble in water because it contains a hydroxyl (–OH) group that forms hydrogen bonds with water molecules.
