Homework Help: Can anyone get me on the right track?

  1. Aug 24, 2007 #1
    Can anyone get me on the right track???

    A solution contains the folllowing ions, each at a 0.1 M concentration.

    Ag+(aq), Ca2+(aq), Ni2+(aq)

    write out a procedure by which these ions may be sparated form each other and from the solution, clearly indicating the order of separation and when filtering should be done.

    Please and thankyou...

    Well, here's a hint: the least reactive of substances are the most easily displaced from a solution, so the order of separation would clearly be from the least reactive to the most.

    hmmm...I am still confused as to what kind of a procedure, what does it mean by this?

    If you place a strip of copper into a silver nitrate solution, the copper would force (displace) the silver out from the solution, right? The concept is basically the same here.
