Hi everyone,

I'm slightly confused between the two equations for the reaction of [Cu(H20)6]2+ and Xs NH3. It says that the reaction Starts with Cu(H20)4(OH)2 but why would it not start with [Cu(H20)6]2+ instead as it is the metal - aqua ion that it is reacting with not the aqua ion that has reacted with NaOH.

Thank you in advance

Because it's already reacted partially with NH3

[cu(H2O) 6]^2+ 2NH3---> [Cu(H2O)4(oh)2] + 2nh4+. (equation for copper and ammonia when it's not in excess)
