The amount of zinc produced is 10.83 g.
given that :
current , I = 11.7 A
time , t = 45.6 min = 2736 sec
the expression is given as :
W = ZIt
W = amount of the substance deposited
I = current in ampere = 11.7 A
t = time in sec = 2736 sec
Z = M / nF
where,
M = molecular mass = 65.3 g/mol
n = no. of electrons = 2
F = faraday constant = 96500 C
W = (65.3 / 2 × 96500 ) 11.7 × 2736
W = 10.83 g
Thus, when molten zinc chloride (zncl2) is electrolyzed, zinc is deposited at the cathode. the amount of zinc produced if a current of 11.7 a is passed through the electrolytic cell for 45.6 min is 10.83 g.
