Faraday's laws of electrolysis: mass deposited = (M × I × t) / (n × F), where M is molar mass, I current, t time, n electrons.
단계별 가이드
- 1Input current, time, substance, electrons transferred
- 2Calculate moles and mass of product
- 3Determine Faraday efficiency
풀어진 예시
입력
Electroplate Cu: 1 A × 3600 s = 1.19 g Cu deposited (96,485 C/mol, 2 e⁻)
결과
Efficiency typically 85-95%
피해야 할 일반적인 실수
- ✕Using wrong number of electrons per atom
- ✕Not accounting for overpotential
자주 묻는 질문
Why is current efficiency < 100%?
Side reactions (water splitting, hydrogen evolution) compete with desired reaction.
