How can we tell which part of an acid/base molecule is a spectator ion and doesn't react?

You can tell when you write out the net ionic equation and the ion is "by itself" (not part of a molecule) as both a product and a reactant. Like in a reaction between NaOH and HCl, I believe both Na and Cl would both be considered spectator ions since they would remain Na+ and Cl- ions when left in the aqueous solution (since NaCl dissociates in water).
