I'm having trouble understanding the following reactions we did in lab and I am not sure our data is very good.
CuSO4 + NaOH yields a blue precipitate. Which I understand is Cu(OH)2. I get this.
Next we add NH3 to the solution above and nothing obvious changes. I think the precipitate may have dissolved. What is happening here?
After this we created a new solution but this time we added CuSO4 to the NH3 and then we added the NaOH. Yet again we just got a blue solution and I am not sure what happened.
Finally we just mixed NH3 and CuSO4 which produced a light blue precipitate.
Can someone please explain to me what is going on in all three reaction above.
