Which symbol denotes the state of a substance dissolved in water in a chemical equation?
Answer and explanation
Correct answer: (aq)
The symbol (aq) means aqueous, so it is used when a substance is dissolved in water. For example, NaCl(aq) represents sodium chloride present as ions in an aqueous solution. The symbols (s), (l), and (g) instead indicate solid, liquid, and gaseous states. Therefore (aq) is the only option that describes a substance dissolved in water, making option D correct.
