Net Ionic Equations
« on: March 18, 2014, 12:22:44 PM »
I'm having trouble with net ionic equations.  I know the principles of net ionic equations (spectator ions aren't included) but how do I know which ions are spectators and which are hydrolyzed? 

For example: Copper (II) nitrate and Water: Cu(NO3)2 + H2O --> 2HNO3 + CuO, correct?  If so, what is the net ionic equation?  I'm really confused!

This is not a correct reaction equation if you ask me (CuO is an unlikely product here).

But, first of all - why don't you write all things that are dissociated as dissociated?

Okay so..

Cu + 2NO3 + H2O --> what?  I'm so confused!  I wish my professor would teach us these things.

You are ignoring charges - that will never help you.

What do you know about copper hydroxide? Its solubility?

It's insoluble, right?  Cu(OH)2?

Yes.

I'm really lost, can you provide me with some guidance?

Hydrolysis means copper will - to some extent - react with water, producing insoluble hydroxide (and something else).
