Rohan arranged three coulometers in series and passed one faraday of charge for a definite time to all three electrolytes as shown in the picture given below:
(a)[1.0]
What will be ratio of number of moles of positive ions liberated at cathode in each coulometer?
(b)[1.0]
If he passed 4825 coulombs of charge through the electrolytes, how many gram-equivalent of copper will be deposited at the cathode?
Answer
Answer (a)
Official answer key
1: 1: 2
Answer (b)
Official answer key
1 g-equivalent = 96500 C
x g-equivalent = 4825 C
$=\frac{4825}{96500}=0.05$ g-equivalent.
