Current Electricity Charging Discharging Of Capacitors Question 57
Question: The amount of charge required to liberate 9 gm of aluminium (atomic weight = 27 and valency = 3) in the process of electrolysis is (Faraday’s number = 96500 coulombs/gm equivalent)
Options:
A) 321660 coulombs
B) 69500 coulombs
C) 289500 coulombs
D) 96500 coulombs
Show Answer
Answer:
Correct Answer: D
Solution:
Equivalent weight of aluminium $ =\frac{27}{3}=9 $ So 1 faraday = 96500 C are required to liberate 9 gm of Al.
