  1. Question 1

    Q1. A conductivity cell filled with 0.1 M KCl has a resistance of 100 Ω. The cell constant is (conductivity of 0.1 M KCl = 1.29 S/m)?

    • A) 12.9 m^-1
    • B) 1.29 cm^-1
    • C) 129 m^-1
    • D) 12.9 cm^-1

    Answer: 129 m^-1

    Explanation: Cell constant = conductivity * resistance = 1.29 S/m * 100 Ω = 129 m^-1.
