Homework Help: Simple Displacement Reactions & Balancing Chemical Reactions

  1. May 10, 2013 #1
    1. The problem statement, all variables and given/known data

    Complete the simple displacement reactions and balance any chemical reactions.

    2. Relevant equations

    copper + silver nitrate → __________ + ____________

    3. The attempt at a solution

    Since copper on the periodic table can be Cu2+ or Cu+, my solution was
    copper + silver nitrate → copper (I) nitrate + silver

    The answer says: copper (II) nitrate. I don't know why this works when NO3- has a 1- charge.

    Cu2+ is the most common and most stable copper ion, especially in aqueous solutions. Charge on NO3- doesn't matter, as it is only a spectator.
