Of course, excuse me, we had de equilibrium of [Fe][/3+] + SCN-
[FeSCN][/2+] dissolved in H2O given. We knew that with warming up the equilibrium shifts to the left side, so the solution ( in H2O) turns lighter.
The experiment we had to do showed that if we first added FeCl to the solution and than warmed up again, the equilibrium shifts to the right side, because the solution turned dark red.
The equilibrium dissolved in H2O without any adittions or warmth is normal red. none time in the complete experiment there was sediment.
I have to explain why the equilibrium shifts to the right side suddenly with warming up, after adding HCl. but I don't find an explanation.
