The number of electrons delivered at the cathode during electrolysis by a current of \( 1\text{ ampere} \) in \( 60\text{ seconds} \) is _________. (charge on electron \( = 1.60 \times 10^{-19}\text{ C} \))

  1. A
    \( 7.48 \times 10^{23} \)
  2. B
    \( 6 \times 10^{23} \)
  3. C
    \( 6 \times 10^{20} \)
  4. D
    \( 3.75 \times 10^{20} \)
View Answer & Solution

Correct answer · Option D

\( 3.75 \times 10^{20} \)

Explanation

Number of electrons \( N = \frac{I \times t}{e} = \frac{1 \times 60}{1.6 \times 10^{-19}} = 3.75 \times 10^{20} \).
