Ions in Water

Soluble ionic compounds dissociate into hydrated ions. Equations label aqueous species with (aq), while conductivity provides evidence for mobile charge carriers.

Core checkpoint: Distinguish dissolving into molecules from dissociating into ions.

Which statement best captures the core checkpoint for Ions in Water?
