Homework Help: Reactions in Solution

  1. Sep 26, 2010 #1
    1. The problem statement, all variables and given/known data

    What is produced when NH3 is mixed with CuSO4(aq)?

    What is produced when H2SO4(aq) is mixed with Cu(NH3)4+2?

    2. Relevant equations


    3. The attempt at a solution

    For the first one, I'm thinking I should treat ammonia as a Group 1 metal and do a single replacement, but I'm not sure how this would work out.

    For the second one, I have no clue how to start. Would the hydrogen pair up with the copper?

    Thanks in advance for the help.

    For the first you are right.
    Same of the second you treat SO4 and NH3 group 1 and do a double replacement

    This is b/c they are polyatomic ions

    What is pH of ammonia solution?

    What do you know of copper hydroxide solubility?

    What do you know about ammonia copper complex?

    What happens to ammonia in the solution of strong acids?

    see when I looked at it, it just seemed to be a balancing sort of problem, like you get in grade school, just to teach you how to do it. Usually you ignore those sort of things for those problems.

    But if it is more advanced then you should def look at what he said
