SUMMARY

The discussion clarifies that NaCl (aq) specifically refers to sodium chloride dissolved in water, resulting in the presence of Na+ and Cl- ions. It emphasizes that the term "aqueous" indicates the solution contains water, which is crucial for understanding the chemical behavior of the dissolved salt. The distinction between liquid and aqueous states is highlighted, with "aqueous" denoting a solution where water is the solvent, separating the salt into its ionic components. This understanding is essential for accurately interpreting chemical reactions involving NaCl in aqueous solutions.

What are we referring to when we denote, say, NaCl (aq)?

Are we referring to the dissolved NaCl (Na+ and Cl-)? Are we speaking of the solution as a whole (the dissolved NaCl and water)?

Also, how does the liquid state differ from an aqueous?

(aq) means water is definitely present. Whether it matters or not for a particular case is another question.

So, NaCl (aq) would imply Na+ and Cl- ions, plus water if it is relevant to the reaction at hand?
 
Yes.
