Examples :

1.      Fe3+ (aq) + SCN- (aq) <---> [Fe(SCN)]2+ (aq)


When a little SCN- sol is added, some SCN- ions will react with Fe3+ ions to produce more [Fe(SCN)]2+. The position of the equilibrium will shift to the right & the intensity of the red sol increases.

When some of Fe3+ / SCN- sol is removed, position of equilibrium will shift to the left so as to increase the amount of these ions & the intensity of red colour decreases.

Tips for remembering :

When concentration of reactants increase, equilirbium will…
