  1. Apr 11, 2007 #1
    Please help! :confused:

    1. The problem statement, all variables and given/known data[/b
    - I need to complete and balance Au2(SO4)3 + Ba ------>
    - what type of reaction is this?
    is this a redox reaction?
    will the reaction go from left to right?

    2. Relevant equations

    3. The attempt at a solution
    2Au+ 3SO4 + Ba?????????

    If the reaction does occur (I don't have the electric potentials of Au and Ba handy) it is indeed a redox reaction. Barium replaces gold...

    Write out the half cell reactions for Au+3 and Ba and go from there. Treat the sulfate as a spectator ion.
