Consider an Aqueous Solution Which Is 0

Multiple Choice

Consider an aqueous solution which is 0.020 M in Pb²⁺ and 0.20 M in Ag⁺. If concentrated potassium iodide solution (so that volume changes may be neglected) is added gradually with good stirring to this solution, which precipitate will form first? Ksp for PbI2 = 7.1 × 10^-9; for AgI = 8.31 × 10^-17

A) PbI₂
B) KI
C) AgI
D) PbI₂ and AgI precipitate together
E) Ag₂[PbI₄]
