The state symbol for anything in aqueous solution is (aq).
State symbols represent the physical state of a substance. The common symbols are (s), (l), (g), and (aq).
(aq) means that the substance is dissolved in water.
We could represent the dissolving of NaCl in water as
NaCl(s) → NaCl(aq)
We know that NaCl dissociates into Na⁺ ions and Cl⁻ ions in aqueous solution. We can also write its dissolving as
NaCl(s) → Na⁺(aq) + Cl⁻(aq)
Glucose does not dissociate into ions. So we represent the dissolving of glucose in water as
C₆H₁₂O₆(s) → C₆H₁₂O₆(aq)
