To produce a mass of 6. 38 g al using a current of 12. 50 amps the time required would be 7207.4 minutes.
<h3>What is faraday law?</h3>
It states that the chemical which is getting decomposed because of the flow of current within an electrolyte is directly proportional to the quantity of electricity passing through it.
W= Z × I × t Z = 1 coulomb
I = current
t = time
substituting the values
Z= 96500/Eq.wt
Al 3+ +3e − →Al n= 3
so, Eq= 27 / 3 = 9
t = W × Z / I
t = 9 × 96500 / 12.50
t = 7207.4 minutes.
Therefore the time required would be, 7207.4 minutes.
