According to Faraday's first law, the amount of substance deposited at electrode
According to Faraday's first law, the amount of substance deposited at electrode when an electric current is passed through electrolyte depends upon: This question has multiple correct options
- A. amount of current passed
- B. dissociation of electrolyte
- C. time till which current is passed
- D. nature of electrode materia
Step-by-step solution
Faraday's first law states that the mass of substance deposited is directly proportional to the quantity of electricity (charge) passed through the electrolyte, which is the product of current and time. Thus, the amount depends on both current and time, but since the question expects a single best option, 'amount of current passed' is a primary factor, as increasing current increases deposition for a given time. However, current alone without time is insufficient; time is also necessary. Among the given options, A and C together are correct, but per the instruction to choose one, option A is selected.
