Calculation of mass of Cl2 produced

  • First, we need to calculate the amount of charge that passes through the solution using the formula:


    • Charge = Current x Time

    • Charge = 1A x 30 minutes

    • Charge = 30 coulombs


  • Next, we need to calculate the amount of NaCl that is electrolyzed using Faraday's law:


    • 1 mole of electrons = 1 Faraday of electricity = 96500 coulombs

    • Number of moles of electrons = Charge / 96500

    • Number of moles of NaCl electrolyzed = Number of moles of electrons / 2 (since NaCl produces 1 mole of Cl2 for every 2 moles of electrons)


  • Finally, we need to calculate the mass of Cl2 produced using its molar mass:


    • Mass of Cl2 = Number of moles of Cl2 x Molar mass of Cl2

    • Molar mass of Cl2 = 2 x Atomic mass of Cl = 2 x 35.5 = 71 g/mol




Answer: The mass of Cl2 produced when 1A current is passed through NaCl solution for 30 minutes is 0.66g (Option B).
