engineering chemistry MCQ #2780

  1. Question 1

    Q1. The conductivity of a saturated solution of AgCl is 1.86 × 10⁻⁶ S / cm. The molar conductivity of AgCl at infinite dilution is 138 S cm² / mol. The solubility of AgCl is

    • A) 1.35 × 10⁻⁵ M
    • B) 1.35 × 10⁻³ M
    • C) 1.35 × 10⁻² M
    • D) 1.35 × 10⁻¹ M

    Answer: 1.35 × 10⁻⁵ M

    Explanation: Using Λ_m = κ / c, we get c = κ / Λ⁰_m = 1.86 × 10⁻⁶ / 138 = 1.35 × 10⁻⁵ M.
