Electrochemistry - Result Question 64

####13. In the electrolytic cell, flow of electrons is from

$(2003,1 M)$

(a) cathode to anode in solution

(b) cathode to anode through external supply

(c) cathode to anode through internal supply

(d) anode to cathode through internal supply

Show Answer

Answer:

Correct Answer: 13. (c)

Solution:

  1. In electrolytic cell electrolysis occur at the cost of electricity : At cathode : $M^{n+}+n e \longrightarrow M$

At anode : $\quad X^{n-} \longrightarrow X+n e^{-}$

(electron supplied to anode)

Therefore, electron is moving from cathode to anode via internal circuit.
