Question

(a) Write Faraday's second law of electrolysis.
(b) Draw labelled diagram of standard Hydrogen electrode.

Answer 1

(a) Faraday's second law of electrolysis:
When same amount of electricity is passed through different cells containing different electrolytes and arranged in series, the amounts of substances oxidized or reduced at the respective electrodes are directly proportional to their chemical equivalent masses.
(b) The labelled diagram of standard Hydrogen electrode is as shown.
