Which symbol represents an aqueous solution in a chemical equation?
Answer and explanation
Correct answer: (aq) — aqueous solution
The governing concept is the notation for physical state and solution medium. When a substance is dissolved in water, the equation marks it as aqueous with (aq), so option D is correct. The other symbols indicate different conditions: (s) is solid, (l) is liquid, and (g) is gas. Thus (aq) specifically communicates water-based dissolution, not merely that the substance is flowing or liquid.
