Thermal-Chemical Effects of Currents


   
 
Numerical 01
01. A current of 0.50 ampere is passing through a CuSO4 solution. How many Cu++ ions will be deposited on cathode in 10 seconds?
 
Suggested solution:
 
Current I=0.50 A
 
Time t=10s
 
Each Cu++ ion carries a charge of two electrons. Let n be the number of copper ions.
 
Then
 
Charge q = n x 2e
 
Now,
