The symbol (aq) is used in a chemical equation to indicate that a substance is in an aqueous solution, meaning it is dissolved in water. This is essential for understanding the state of compounds during reactions. For example, NaCl in water is represented as NaCl (aq). ;
The symbol (aq) indicates that a substance is dissolved in water in a chemical equation. This notation is important for understanding the physical state of reactants and products during chemical reactions. For instance, NaCl (s) dissolves in water and is represented as Na + (aq) + Cl − (aq).
