Reaction direction question:

[Mathman23]

Hi

Here is a reaction: Fe^(3+) + SCN^(-) <---> FeSCN^(2+)

If I add some extra KSCN to the above equilibrium reaction, in which direction will it react according to the law of chemical equilibrium?

Any hits?

Thanks for Your answer in advance.

Sincerely Yours

No "hits" but here's a hint: If you add more KSCN it will dissolve and dissociate so there will be more SCN ion. Which way does the reaction go in order to reduce the excess SCN ion?
