When is the aqueous state symbol (aq) used in a chemical equation?
Answer and explanation
Correct answer: When the substance is dissolved in water
The state symbol (aq) means aqueous: the substance is dissolved in water and exists as part of an aqueous solution. For example, NaCl(aq) represents sodium chloride dissolved in water. Therefore option A is correct. The symbols (s), (l), and (g) separately indicate solid, pure liquid, and gaseous states; (aq) is not simply a general symbol for every liquid.
