Passage / Comprehension

Paragraph: 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 $P$ . Addition of zinc chloride to $P$ in a slightly acidic medium results in a sparingly soluble complex Q.

Question: The number of moles of potassium iodide required to produce two moles of $P$ is

Answer:

2.00

Solution:

$KI + K_{3} [Fe (CN)_{6}] ⇌ K_{4} [Fe (CN)_{6}] + \frac{1}{2} I_{2}$ Moles of $KI$ required $= 2$
