Question

A metal part of an electrochemical cell which gains or loses electrons is called ____.

A) Cathode.
B) Anode.
C) Electrolyte.
D) Conductor.

Answer 1

In an electrochemical cell, the anode loses electrons and is considered negative, while the cathode gains electrons and is considered positive.

Step-by-step explanation:

The metal part of an electrochemical cell which gains or loses electrons is called an electrode. There are two types of electrodes in electrochemical cells: the anode and the cathode.

The anode is the electrode where oxidation occurs and electrons are lost, whereas the cathode is the electrode where reduction occurs and electrons are gained. In a typical electrochemical cell setup, electrons move from the anode to the cathode through a conductive wire, facilitating electron transfer for the redox reactions to occur.

The anode is often labeled as the negative electrode due to the production of electrons, and the cathode is known as the positive electrode.
