• Net ionic equations only show the species that are reacting or changing in a chemical reaction
• Chemical species that don’t change are called spectator ions
• A few reminders
> Soluble ionic compounds dissociate into ions
> Insoluble ionic compounds do not dissolve or dissociate – their state remains solid
> Strong acids dissociate into H+ ions and an anion
> Elements exist as atoms or molecules -­‐ they do not have a charge
