JEE AdvancedChemistrySalt AnalysisNumerical+3 / −1
When potassium iodide is added to an aqueous solution of potassium ferricyanide, a reversible reaction is observed in which a complex P\mathbf{P}P is formed. In a strong acidic medium, the equilibrium shifts completely towards P\mathbf{P}P. Addition of zinc chloride to P\mathbf{P}P in a slightly acidic medium results in a sparingly soluble complex Q.The number of zinc ions present in the molecular formula of Q\mathbf{Q}Q is ‾\underline{\hspace{2cm}}​.
