Talk:Tetramminecopper(II) sulfate

Source

This page really needs a source as to the composition of the solid compound formed (although I am willing to believe that it is indeed the tetrammine complex). In solution, there are a variety of [Cu(H₂O)_x(NH₃)_6−x]²⁺ complexes formed, depending on the concentration in ammonia. Physchim62 10:53, 22 July 2005 (UTC)[reply]

I'm not a chemist, but am very interested in these topics. I saw a good explanation of coordination compounds in http://www.chemguide.co.uk, and a reference to the tetramminecopper complex, more precisely, tetraamminediaquacopper coplex, as they call it, at http://www.chemguide.co.uk/inorganic/complexions/ligandexch.html#top and http://www.chemguide.co.uk/inorganic/complexions/aquanh3.html#top and http://www.chemguide.co.uk/inorganic/transition/copper.html#top; per the last link, I would think that once we get the ammonia-containing complex, the resulting salt would be a di-hydrate, not a monohydrate as the article tells (but this is only my guess). I think these links could be a good starting point. --Paiconos 15:25, 20 September 2005 (UTC)[reply]

By the way (for a chemist), would we have ligand exchange if we used ammonium ions (let's say, from ammonium sulfate) instead of ammonia? Paiconos

Preparation method

I have prepared cuprammonium sulfate (or tetramminecopper sulfate) by reacting dilute household ammonia with dilute copper sulfate solution. I don't know if you really need to use a saturated solution of ammonia and copper sulfate. When I added small amounts of ammonia to copper sulfate, it produced the bluish-white copper hydroxide. But when I added more ammonia, the vivid blue color of the cuprammonium ion showed up. Just a hint.--98.221.179.18 (talk) 21:16, 19 February 2010 (UTC)[reply]

Incorrect spelling

Somebody PLEASE fix the spelling of the title. It requires another 'A'. 124.184.160.206 (talk) 03:27, 21 April 2012 (UTC)[reply]

what do you suggest? Ammonia complexes are referred to as ammines. Wierd but that's the way it seems to be.--Smokefoot (talk) 03:54, 21 April 2012 (UTC)[reply]

Do you mean "tetraamminecopper(II)" rather than "tetramminecopper(II)"? --Ben (talk) 22:42, 22 April 2012 (UTC)[reply]

Yes, OP is correct, it's spelt "Tetraamminecopper(II)" so the title is currently incorrect. --Radiotrefoil (talk) 01:58, 17 June 2012 (UTC)[reply]
