Question

In equilibrium: SCN⁻(aq) (colourless) + Fe⁺³(aq) (yellow) ⇌ [Fe(SCN)]²⁺(aq) (deep red). If thiocyanate ions are added in equilibrium mixture

Answer: C

💡 Solution & Explanation

Adding more reactant (SCN⁻ ions) will cause the system to shift in the forward direction according to Le Chatelier's principle. This increases the concentration of the product [Fe(SCN)]²⁺, deepening the red colour. Therefore, correct answer is C.
