Unmatched characteristic of complex [PdCl2(H2O)2(NH3)2]^2+ is : — Coordination Compounds Chemistry Question

💡 Solution & Explanation

Step 1: Determine the amount of AgCl precipitate obtained: 28.7 g / 143.5 g/mol = 0.2 mol of AgCl. Step 2: Since the solution was 0.1 M, a yield of 0.2 mol of precipitate from a standard 1 L volume of 0.1 M solution corresponds to exactly 2 moles of ionizable Cl^- ions per mole of the complex. Step 3: To have 2 chloride ions outside the coordination sphere as counterions, the structural formula must be [Cr(H2O)5Cl]Cl2 . H2O, which corresponds to option (b).
