How would you use Le Chatelier's principle to explain the different colors found in the following equilibria? #Ni^(2+)#, #NH_3# , and #[Ni(NH_3)_6]^(2+)#?

Well, what are the different colours, and what experiment did you do?

Explanation:

We gots an equilibrium...

#Ni^(2+) + 6NH_3(aq)rightleftharpoons [Ni(NH_3)_6]^(2+)#

You did the experiment; what did you see?

And old Le Chatelier's principle states that when #"a system at equilbrium is subject to an external "#
#"perturbation, the equilibrium will move so as to offset"# #"the external perturbation"#.

And the point to note here is that #"OFFSET "!=" COUNTERACT"#.
