how do you explain why the addition of silver nitrate to the Fe/SCN equilibrium had an effect on the equilibrium, even though neither silver ion nor nitrate ion is written as part of the equilibrium reaction?

Respuesta :


The addition of silver nitrate to the Fe/SCN equilibrium affects the Ag+ ion. Ag+ reacts with the SCN to form a precipitate. It is not a part of the equilibrium reaction, but it changes the concentration and removes SCN ions. This causes equilibrium to favor the reactants and make SCN to reach equilibrium.
