  1. Question 1

    Q1. If the molar solubility of Lead (II) chloride (PbCl2) is represented by 's', what is the correct expression for its Solubility Product (Ksp)?

    • A) s^2
    • B) 2s^2
    • C) s^3
    • D) 4s^3

    Answer: 4s^3

    Explanation: Ksp = [Pb][Cl]^2 = (s)(2s)^2 = 4s^3. Option C is wrong because it forgets to square the chloride concentration and the coefficient.
