Why is water called the 'universal solvent'?

Solution

  1. 1
    Water is polar — the O–H bonds create a molecule with a partial negative end (O) and partial positive end (H).
  2. 2
    This polarity allows water to dissolve many ionic compounds (by attracting ions) and polar molecules.
  3. 3
    No other common solvent dissolves as many different substances as water.

Answer

Water’s polarity allows it to dissolve many ionic and polar substances.\text{Water's polarity allows it to dissolve many ionic and polar substances.}
The term 'universal solvent' is an exaggeration — water does not dissolve everything (e.g., oil is nonpolar and does not dissolve well in water). The principle 'like dissolves like' governs solubility.
