Strategy:
 Determine the number of ionizable chloride ions outside the coordination sphere. Non-ionizable ligands tightly bound inside the sphere will not precipitate.

Step 1: Analyze the complex
Complex: .
Only the 2  ions outside the brackets are ionizable and will react with .
Therefore, 1 mole of complex yields 2 moles of precipitate.

Step 2: Calculate moles of chloride
Moles of complex = Molarity  Volume = .
Moles of ionizable .

Step 3: Calculate volume of 
Reaction requires 1 mole of  p
