I need to figure what reaction will occour when Ammonia is poured into a copper(II) nitrate solution. Yes, there is water present. Here is the equation i got, but i feel like i am wrong: 3Cu(NO3)2 + 4NH3OH --> 2Cu(OH)2 + Cu(NH3)4 + 3NO3
I think there is OH because the Ammonia is a base and by defenition would increase the concentration of OH- ions and the copper would naturally bond to these, but im not 100 % sure.
Also is it the Cu(NH3)4 that makes the dark blue color, or is atleast a darker blue than Cu(NO3)2?
Also what exactly is Cu(NH3)4 called?
