Salt (NaCl) and sugar (sucrose, C12H22O11) are two common solids that are highly soluble in water. Salt dissolves in water by dissociating into its ions (sodium and chloride), while sugar dissolves as molecules. These solubilities make them crucial in various culinary and industrial processes.

FAQs & Answers

  1. Why are salt and sugar soluble in water? Salt dissolves in water by dissociating into ions, while sugar dissolves as molecules, both interacting effectively with water molecules.
  2. What makes a solid soluble in water? A solid is soluble in water if it can interact with water molecules through ionization or molecular interactions, allowing it to disperse uniformly.
  3. Are all solids soluble in water? No, only solids that can interact well with water molecules, such as ionic or polar compounds like salt and sugar, are soluble; others are not.
