Zorluk: KolayFaraday's Laws of Electrolysis and Quantitative Calculations

Calculate the quantity of electricity, in Coulombs, transferred when a steady electric current of 5.0 A5.0\text{ A} is passed through an electrolytic cell for 20 minutes20\text{ minutes}.

Cevap: 6000 C

Cevap

The quantity of electricity transferred is 6000 C6000\text{ C}.
According to Faraday's laws of electrolysis, the total charge QQ passed through an electrolyte is calculated by Q=I×tQ = I \times t. Converting 20 minutes20\text{ minutes} to seconds gives 20×60=1200 s20 \times 60 = 1200\text{ s}. Multiplying by the current 5.0 A5.0\text{ A} gives Q=5.0×1200=6000 CQ = 5.0 \times 1200 = 6000\text{ C}.

Adım Adım Çözüm

1
Convert time from minutes to seconds
t=1200 st = 1200\text{ s}
Electric current in Amperes measures charge per second, so time must be converted to seconds.
2
Calculate electric charge using Q=I×tQ = I \times t
Q=6000 CQ = 6000\text{ C}
The quantity of electricity (QQ) in Coulombs equals current (II) in Amperes multiplied by time (tt) in seconds.
