(B) A solution of 1 liter contains Feft, SCN; and Fe(SCN)'* and reacts following the equation shown as Fe** (pale yellow) + SCN (colorless) 특 Fe(SCN)"+ (red) to an equilibrium state of red color. If we add 0.01 mole of K/SO, to the present solution, the color will change to deep red or to pale yellow? Please explain why adding inert salt will change the color? (5分)
