Electrochemistry 1 Question 13
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:
- 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.
