# 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...

$N {i}^{2 +} + 6 N {H}_{3} \left(a q\right) r i g h t \le f t h a r p \infty n s {\left[N i {\left(N {H}_{3}\right)}_{6}\right]}^{2 +}$

You did the experiment; what did you see?

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

And the point to note here is that $\text{OFFSET "!=" COUNTERACT}$.
