For the reaction
Correct answer: A. intensification of red color.
- A. intensification of red color.
- B. decolorization
- C. yellowing of solution
- D. Decrease in [Fe (SCN )]2+ concentration
Explanation
A) Intensification of red color: The addition of additional SCN- ions will likely intensify the red color of the complex [Fe(SCN)]2+ note that the color changes in chemical reactions can be complex and depend on various factors such as concentration, pH, and temperature. The explanation provided here is based on the general understanding of the reaction given in the question.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
