Electrons in a Voltaic Cell flow from ---------- to -----------

Correct answer: B. Anode, Cathode

  • A. Cathode, Anode
  • B. Anode, Cathode
  • C. Right, left
  • D. None of these

Explanation

In a Voltaic Cell, which is also known as a galvanic cell, electrons flow from the anode to the cathode. The anode is where oxidation occurs, meaning it's the site where electrons are lost as a substance is oxidized. This creates an electron surplus at the anode.On the other hand, the cathode is where reduction occurs. Reduction involves gaining electrons, so the cathode becomes the site where electrons are gained. This balances out the electron flow that started at the anode.Overall, the movement of electrons from the anode to the cathode creates an electric current that can be harnessed to do useful work, such as powering electronic devices.

About Electrochemistry

Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
