CuCl2 + NH3 and also CuSO4 + NH3?
I have a green salt, CuCl2, in H2O. I added NH3 to this solution and it turned blue.
Is it because there are Cu2+ cations?
Likewise, I have a blue salt, CuSO4, with H2O. I added NH3 to this solution and it turned blue.
Is it because there are Cu2+ cations?
These two salts are from an unknown general cation+anion chemistry lab.
I am sure I have Cl- and SO4 2- anions. I was trying to confirm my cations.
Is adding NH3 correct confirm I had copper or is this totally wrong and I do not have copper as my cation?

1) Part One is Right, Copper ions by default in solution are blue!
2) adding NH3 is correct, because the complex ion Cu(NH3)4 2+ is formed, and Cu+2 is in solution and it is the cation. It is not wrong at all, you are absolutely correct!

Ah its been so long. Did the handy ones, not in any order. 2Ba O2 >2BaO + O2( for BaO2 > BaO + O2) 2H2 + 6N2 > 4NH3 ( for H2 + N2 >>> NH3) Ca C O3 + 2H Cl > H2 O + C O 2 + Ca Cl2 ( for CaCO3 + HCl >> H2O + CO2 + CaCl2) 3CuSO4 + 2AL > Al2(SO4)3 + 3Cu (for CuSO4 + Al>>> Al2(SO4)3 +Cu) Do the leisure lol :-p.
