What is the correct difference between the aqueous symbol \((aq)\) and the liquid symbol \((l)\) in a chemical equation?
Answer and explanation
Correct answer: \((aq)\) denotes a substance dissolved in water, whereas \((l)\) denotes a substance in the liquid state.
\((aq)\) means that a substance is dissolved in water and is present as an aqueous solution, for example, \(\mathrm{NaCl(aq)}\). \((l)\) means that the substance itself is in the liquid state, for example, \(\mathrm{H_2O(l)}\). Thus, \((aq)\) does not merely mean liquid; it specifically indicates dissolution in water.
