What is the correct distinction between the symbols ext{(aq)} and ext{(l)} in a chemical equation?
Answer and explanation
Correct answer: ext{(aq)} means the substance is dissolved in water, whereas ext{(l)} means the substance is in the liquid state.
ext{(aq)} denotes an aqueous solution, meaning that the substance is dissolved in water; for example, ext{NaCl(aq)} . ext{(l)} only indicates that a substance is in the liquid state; for example, ext{H}_2 ext{O(l)} . Thus, option B incorrectly reverses the meanings of the two symbols.
