Lead Ions Can Be Precipitated from Aqueous Solutions by the Addition

question 174

Multiple Choice

Lead ions can be precipitated from aqueous solutions by the addition of aqueous iodide: Pb²⁺ (aq) + 2I^- (aq) → PbI₂ (s)
Lead iodide is virtually insoluble in water so that the reaction appears to go to completion. How many milliliters of 3.550 M HI(aq) must be added to a solution containing 0.600 mol of Pb(NO₃) ₂ (aq) to completely precipitate the lead?

• A)2.96 × 10^-3
• B)338
• C)169
• D)0.169
• E)0.338
