Are the two chemical equations correct?
Thread Content
Cu(NH3)2+H-+Cl-+H2O = Cu(OH)2+(NH4)Cl; CuCl2+NH3·H2O = Cu(OH)2+(NH4)Cl
There shouldn’t be any problems, right? What is the original poster trying to point out?
I don’t think that’s right; that subscript should be below, right? The ions on both sides of the first equation aren’t balanced
There’s nothing major wrong with the reaction; it’s just that the equation is written incorrectly – at least the charge balance is off: lol.
I read in a literature article that both reactions produced copper chloroxide and ammonia; I thought that was incorrect, which is why I’m sharing my own opinion – please verify it! Thank you all for your support. :)
It must be wrong. I’m not very skilled; I’m not sure if this modification is correct. Please advise me. Cu(NH3)2+ + H+ + Cl- → Cu2+ + (NH4)Cl; CuCl2 + 2NH3·H2O → Cu(OH)2 + 2(NH4)Cl
Copper ammonia solution and copper chloride are neutralized and inoculated via crystallization to produce crystalline basic copper chloride (TBCC): Main reactions: 2CuCl2 + 2Cu(NH3)4Cl2 + 2HCl + 7H2O = 3CuO•CuCl2•4H2O + 8NH4Cl; 4Cu(NH3)4Cl2 + 10HCl + 7H2O = 3CuO•CuCl2•4H2O + 16NH4Cl; 4CuCl2 + 6NH3•H2O + H2O = 3CuO•CuCl2•4H2O + 6NH4Cl
I think it’s incorrect; firstly, the concentration of copper ions in the copper-ammonia complex solution should be lower than that in the copper hydroxide solution, so the reaction cannot occur
Both reactions are wrong; it’s better not to rely solely on what is written in books
If the final reaction product is acidic: it is copper chloride and ammonium chloride； The basicity is due to copper ammine complexes and ammonium chloride
