What is the correct meaning of the state symbol (aq) in a chemical equation?
Answer and explanation
Correct answer: The substance is dissolved in water
The symbol (aq) means aqueous: the substance is present in a solution made with water, usually dissolved in water. For example, NaCl(aq) represents sodium chloride dispersed as ions in water. Thus option B is correct. The symbols (s), (l), and (g) separately indicate solid, liquid, and gaseous states, so options A, C, and D confuse aqueous solution with ordinary physical states.
