Faraday’s II Law of Electrolysis: If the same quantity of electricity is passed through different electrolytic cells, connected in series containing different electrolytic solutions or melts, the amounts of substances deposited or liberated or dissolved are directly proportional to their equivalent weights. Mathematically, m1/m2 = E1/E2 . Followup questions 2) The electric …

Faraday’s law of induction may be stated as follows: The induced emf ε in a coil is proportional to the negative of the rate of change of magnetic flux: B d dt ε Φ =− (10.1.3) For a coil that consists of N loops, the total induced emf would be N times as large: B d N dt ε Φ =− (10.1.4) 10-3. Combining Eqs. (10.1.3) and (10.1.1), we obtain, for a spatially uniform field B, G (cos

Cathode reaction: Cu 2+ + 2e – → Cu (s) In this case, 2 Faradays of electricity are required to deposit one mole of copper atom 63.5g. This means 2 × 96500 C liberates 63.5g of copper. Quantity of electricity passed = I×t = 4×1800C. So, if 2×96500 C liberates 63.5g, then 4×1800C will liberate = 2.4g of copper.
