Which symbol is used to indicate the aqueous state in a chemical equation?
Answer and explanation
Correct answer: (aq)
The governing convention is that state symbols identify the physical condition of each substance in a chemical equation. The symbol (aq) means aqueous: the substance is dissolved in water. Thus option D is correct; NaCl(aq), for example, represents sodium chloride dissolved in water. In contrast, (s) means solid, (l) means liquid, and (g) means gas, so none of those indicates an aqueous solution.
