Unknown green salt with anion Cl-. Finding Cation....(Gen Chem II Lab)?

Question

I am in Gen Chem II lab studying general unknown salts. My salt was green, like lime green?

I went through the anion process and found Cl-.

Afterwards, I dissolved some of the salt in H2O. I mixed this solution with NH3. 
The solution turned dark blue like aqueous Copper (II).

Do I have CuCl2?

I was told I might of done the process wrong because I did not remove my anion...... 
and I was told I might of done the process wrong because I did not add HCl, Ta, NH3, centrifuge, decant, and etc... (a whole process of precipitating group II ions).

However, I was with my lab professor and she said I should go ahead and use the new solution and just add NH3, but she's not the main lab professor.. so I just want to make sure I did this right.

Thanks!

Yes, you have detected Cu2+ even though you haven't followed standard procedure.

As i'm caught in between many somewhat some diverse perception structures, i'm going to be finding at Easter this weekend. yet i'm going to be calling it Ostara, as i'm rather valuable i'm closer to Pagan than Christian. right here contained in the united kingdom, I pronounced the equinox early this morning. i think of it replaced into around 6 - 6:30. Or a minimum of it replaced into in accordance to my satellite tv for pc tracker on my cellular. At 6:22, the graphical representation of the sunlight popped northward in user-friendly terms slightly pixel, and grew to grow to be completely aligned with the equator. It replaced right into a magickal 2nd for me certainly, quite as a results of fact the 'day/night line' straightened up so as that there replaced into completely equivalent gentle/darkness on my international map. i'm going to could desire to attend til September to witness a 2nd like that lower back.
