Homework Help: Net Ionic Equation - Need Help

  1. Sep 28, 2009 #1
    I've been struggling with this for a while now. Cu(ClO4)2 is soluble so it should drop from both sides of the net ionic equation, right? Leaving only H20. Am I missing something?

    Cu(OH)2 is insoluble. There is a reason why it is marked with (s).

    But if you have something solid like Cu(OH)2, you need to leave it in the equation, regardless of whether any of its ions (such as Cu2+) have separated on the other side of the equation.
