Question

When the current is turned on, electrons flow from ______ (anode/cathode) to ______ (anode/cathode). The cathode becomes the ______ (negative/positive) electrode by which electrons ______ (enter/leave) the electrolyte.

Answer 1

When the current is turned on, electrons flow from anode to cathode. The cathode becomes the negative electrode by which electrons leave the electrolyte.

Explanation:

In an electrolytic cell, the battery pumps electrons into the cathode, making it the negative electrode. These accumulated electrons then enter the electrolyte to reduce positive ions (cations). Meanwhile, electrons leave the anode to return to the power source, completing the electrical circuit.
