Experiment 6.1: Iron(III) Thiocyanate Equilibrium
A pale orange diluted iron thiocyanate solution is treated alternatively with excess iron(III) or excess thiocyanate.
The color gets deep red in both cases.
The equilibrium can be described simplifying according to the equation:
The addition of water shifts the equilibrium in direction of the reactants, the addition of iron(III) or thiocyanate again in direction of the products.
