When potassium iodide is added to an aqueous solution of potassium ferricyanide, a reversible reaction is observed in which a complex P is formed. In a strong acidic medium, the equilibrium shifts completely towards . Addition of zinc chloride to in a slightly acidic medium results in a sparingly soluble complex .
The number of moles of potassium iodide required to produce two moles of P is ____.
The number of moles of potassium iodide required to produce two moles of P is ____.
Answer: 2
Solution
The reaction is:
Complex P is (potassium ferrocyanide).
From the stoichiometry, 1 mole of KI produces 1 mole of P.
Therefore, to produce 2 moles of P, 2 moles of KI are required.
