• Well, as net charge is always the same, you are free to exchange any. I do remember water being involved in Cobalt chloride complexes, with change in lattice water. The same must apply for ammonia, too. – William R. Ebenezer Feb 4 at 11:54
• Your question is not very clear. Do you mean how to make the difference between the 2 compounds if you have them in 2 different jars? Or do you mean how to study that exchange in a solution? – SteffX Feb 4 at 16:14
