I need help on this question:

"The equilibrium concentration of FeSCN2+ ions in each reference solution listed below is essentially equal to the concentration of SCN- ions in solution before any reaction occurs." Use Le Chatlier's Principle to explain why this statement is true.

I don't understand why the statement is true, even though I know what Le Chatlier's Principle states.

I would say it is a simple stoichiometry, no need for LeChatelier's principle. Equilibrium constant for the reaction is high enough.

Here is some of the stuff I had left out, the table:

[Borek]

I see what they mean. Compare concentrations.

The concentration of Fe is higher than concentration of SCN. How do I explain how the stateman is true though? It's talking about Keq, and I don't know what the equilibrium reaction is and how to input Le Chatlier's principle into the statement.

What is the reaction between Fe³⁺ and SCN^-?
