What products are formed when aqueous solutions of Na2SO4, Fe3SO42, and BaCl2 are mixed together ? Can someone help me write out a balanced equation for the reaction that occurs.

  • chemistry -

    Na2SO4(aq) + BaCl2(aq) ==> BaSO4(s) + 2NaCl(aq)

    I don't recognize Fe3(SO4)2. You may mean FeSO4 or Fe2(SO4)3, BaSO4(s) is the end product.

  • chemistry -

    yes I mean Fe2(SO4)3. How come you only used TWO of the reactants for your equation?? What happens with the third one?

  • chemistry -

    BaSO4 is the insoluble material out of all of these. The same thing happens with Fe2(SO4)3.

    Fe2(SO4)3(aq) + 3BaCl2(aq) ==> 3BaSO4(s) + 2FeCl3(aq)

    Both of these reactions are going on at the same time. It is far easier to make everything balance if we write them separately than try to put them together.
