Homework Help: Spectator Ions

  1. Oct 14, 2012 #1
    1. The problem statement, all variables and given/known data
    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?


    2. Relevant equations



    3. 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?

    There's nothing about that in my notes :\

    Then check your book or ask prof. Google.
