Web3 nov. 2016 · Part- A P bI 2(soln) ionises in its solution as follows P bI 2(soln) ⇌ P b2+ + 2I − If the concentration of P bI 2 in its saturated solution is xM then concentration of P b2+ will be xM and concemtration of I − will be 2xM. So Ksp = [P b2+][I -]2 ⇒ 1.4 × 10−8 = x ⋅ (2x)2 ⇒ x3 = 1.4 4 ×10−8 = 3.5 × 10−9 ⇒ x = 1.518 × 10−3
