WebOct 6, 2024 · Faraday's laws of electrolysis are related to the. Atomic number of cation. Atomic number of anion. Equivalent weight of the electrolyte. Speed of the cation. Q3. When the same quantity of electricity is passed through the solutions of different electrolytes in series, the amount of the products obtained are proportional to their. Atomic weights. Faraday discovered that when the same amount of electric current is passed through different electrolytes/elements connected in series, the mass of the substance liberated/deposited at the electrodes is directly proportional to their chemical equivalent/equivalent weight (E). This turns out to be the molar mass (M) divided by the valence (v)
