Redox Reactions And Electrochemistry Question 193
Question: When during electrolysis of a solution of $ AgNO_3, $ 9650 coulombs of charge pass through the electroplating bath the mass of silver deposited on the cathode will be
Options:
A) 1.08 g
B) 10.8 g
C) 21.6 g
D) 108 g
Show Answer
Answer:
Correct Answer: B
Solution:
[b] When 96500 coulombs of electricity is passed through the electroplating bath amount of Ag deposited $ =108g. $
$ \therefore $ When 9650 coulombs of electricity is passed, deposited Ag $ =\frac{108}{96500}\times 9650=10.8g $
