For the equilibrium with Fe3+, SCN- and [FeSCN]2+,
Why does the solution decolour when you add water to it. Do I have to talk about the concentration of Fe3+ and SCN- decreasing, causing [FeSCN]2+ to decrease.
Because when you add other chemicals like potassium thiocynate instead of water, one of the reactant ions decreases, causing [FeSCN]2+ to decrease, but here, surely water doesnt react. Thanks
Chemical Equlibrium?

When a small amount of water is added, the solution is not decolorized. The solution is decolorized only when a plenty of water is added. This is due to the solution is diluted to a great number of times.
This is a question of dilution, not equilibrium.

Color disappears - what does it tell you about concentration of Fe/SCN complex?
concentration of Fe3+ and SCN increasing and
causing [FeSCN]2+ to decrease.
