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