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 0.700 mol of Pb(NO) 3) 2 (aq) to completely precipitate the lead?
A) 2.54 × 10-3
B) 394
C) 197
D) 0.197
E) 0.394
