conc. NH3+CuSO4(aq)-->? | Yahoo Answers

 · Best Answer: The reaction between NH3 and CuSO4 takes place in aqueous solution. Therefore it is more convenient to talk about the reaction between CuSO4 and NH4OH. The NH3 reacts with the water NH3 + H2O ↔ NH4OH. But the equilibrium lies far over to the reactant side, and very little NH4OH is produced.

Redox reaction from dissolving zinc in copper sulfate ...

So what we have here is a solution of a copper sulfate. And copper sulfate is an ionic compound. The copper loses two electrons to the sulfate. So the copper has a positive 2 charge, and the sulfate has a negative 2 charge. This is a cation. This is an anion. So you could imagine it's very easy to dissolve it in a polar solvent like water.
