Given below are two statements : Statement I : The mass of a substance altered at an electrode during electrolysis is directly proportional to the quantity of electricity passed. Statement II : When the same quantity of electricity is passed through solutions of different electrolytes connected in series, the number of moles of the substances deposited is directly proportional to their chemical equivalent weights. In

Step-by-step solution

Statement I is the exact definition of Faraday's first law of electrolysis, hence it is correct. Statement II is incorrect. According to Faraday's second law of electrolysis, when the same quantity of electricity is passed through solutions of different electrolytes connected in series, the masses of the substances deposited are directly proportional to their chemical equivalent weights. The number of moles deposited is inversely proportional to the valency ( n -factor) of the respective ions, not directly proporti
