Question

Quizplus · Accepted Answer

The addition of iron(III) chloride will increase the concentration of Fe3+, shifting the equilibrium to the right according to Le Chatelier's principle. This will increase the concentration of the complex ion [Fe(SCN)16]3-, which is responsible for the red color of the solution. Therefore, the solution will turn more red.
