Question

The number of electrons delivered at the cathode during electrolysis by a current of 1 ampere in 60 seconds is :
(charge on an electron is 1.60×1019C) :

  1. 6×1023
  2. 6×1020
  3. 7.48×1023
  4. 3.75×1020

A
3.75×1020
B
7.48×1023
C
6×1023
D
6×1020
Solution
Verified by Toppr

Q=ne
Q is the amount of electricity passed
n is the number of electrons liberaed at cathode
e the charge of electron
i×t=ne (Q=i×t)
n=i×te
n=1×601.6×1019
n=3.75×1020
