The electrolysis of molten alcl3 for 4.25 hr will produces 35.67g of aluminum metal.
Electrolysis can be described as the process where by electric current is passed through a substance to effect a chemical change.
The mass of the deposited metal can be calculated as
=[tex]W = CEt/96500[/tex]
Given;
t = time taken = 4.25hr = 4.25*60*60 = 15300s
C = Current = 25.0 A
E = Equivalent mass of Aluminum =9
Atomic-mass/valency = 27/3 = 9
If we substitute the values we have;
[tex]W = ( 27*9*15300)/96500[/tex]
= 35.67g
