प्रश्न
State why ‘Water is considered a universal solvent’. Give the reason for the same.
उत्तर
Water is universal solvent: Water dissolves many substances forming aqueous solutions. Not only solids, but gases and other liquids also dissolve in water. When water is put in the glass vessel an extremely small amount of glass dissolves in it. Organic compounds [carbohydrates, proteins] also dissolve in water. Hence water is called a universal solvent.
