Water—due to its polarity and ability to dissolve many different solutes— is often described by which term?

• A. Universal Solvent
• B. Specific Heat Capacity
• C. Adhesion
• D. Water Molecule

Answer: (A)

The key idea is that water’s polarity makes it an unusually versatile dissolving medium. Because water molecules are polar, they orient themselves around charged particles and other polar molecules, forming hydration shells that separate and stabilize solute ions and molecules in solution. This ability to dissolve a wide range of substances—especially ionic compounds and other polar solutes—is why water is described as the universal solvent.

The other terms don’t capture this dissolving power. Specific heat capacity describes how much energy is needed to raise water’s temperature, not how it dissolves substances. Adhesion refers to water’s attraction to other materials, which relates to movement through tubes or on surfaces rather than its dissolving ability. A water molecule is just the basic unit of the substance, not a descriptor of its solvent behavior.
