Which term describes water's ability to dissolve many substances?

• A. Universal Solvent
• B. Interconnectedness
• C. Cultural Awareness
• D. Freezing Point

Answer: (A)

Water’s ability to dissolve many substances comes from its polarity and hydrogen-bonding ability. The molecule has a slightly negative oxygen end and a slightly positive hydrogen end, so it can surround and interact with charged or polar parts of other substances. This makes ions and polar molecules readily separate and become solvated—that is, surrounded by water molecules—so they disperse evenly in the liquid. Because this single property explains why water can dissolve such a wide range of materials (salts, sugars, acids, and many others), the term that best describes it is universal solvent.

Keep in mind that not everything dissolves in water—nonpolar substances like oils don’t dissolve well because they don’t interact strongly with water’s polar molecules. Other terms like interconnectedness, cultural awareness, or freezing point refer to different concepts and don’t describe water’s dissolving power.
