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(NO3) 2(aq) to completely precipitate the lead?
A) 2.54 × 10-3 mL
B) 394 mL
C) 197 mL
D) 0.197 mL
E) 0.394 mL
