Homework Statement


Barium hydroxide is soluble in water. What are the spectator ions in the reaction of a dilute solution of barium hydroxide with hydro-sulfuric acid?


Homework Equations





The Attempt at a Solution


The chemical equation is:
[itex]Ba(OH)_{2(aq)}+H_{2}SO_{4(aq)} \rightarrow BaSO_{4(s)}+2H_{2}O_{(l)}[/itex]
In my notes it says sulfates are soluble except for a few, Ba is one of them.
The ionic equation is:
[itex]Ba^{2+}+6O^{2-}+4H^{+}+S^{2-} \rightarrow BaSO_{4(s)}+4H^{+}+2O^{2-}[/itex]
Not sure on the ionic equation...
Any help because I thought the spectators are the ones that cancel out?

Check your notes on dissociation - how do the bases dissociate? How do the acids dissociate?

Then check your book or ask prof. Google.
