Question

What is an active electrode? Explain with the help of an example

Answer 1

Hint: In the given question firstly we have to define what exactly are the electrodes and then we have to define which are the active ones and how can we determine it and give the proper definition and the characteristics of it. And now we can also say that they are the conductor that we can use in order to make the contact with a nonmetallic part of a given circuit.

Complete answer:
The given question statement asks about the carbon atoms which are active in nature and the elements forming them. We have to provide the basic definition and the other important characteristics for these atoms along with the significance in chemistry and isomerism.
The concept of electrode: It is basically a conductor that we can use in order to make the contact with a nonmetallic part of a given circuit. The electrodes are most commonly used in the electrochemical cells along with the semiconductors like the diodes, and in medical devices.
An active electrode is an electrode which is defined as the metal that can be used in the making of electrochemical cells. These types of electrodes can be easily oxidized or reduced as compared to the other ones. The active electrode is called ‘active’ because it actively participates in the chemical reaction. Also, it is used in electroplating. The most commonly used active electrode is the copper electrode.

Note:
In a vacuum tube or a semiconductor having polarity (diodes, electrolytic capacitors) the anode is the positive (+) electrode and the cathode the negative (−). The electrons enter the device through the cathode and exit the device through the anode. Many devices have other electrodes to control operation.
